Perfect fit. HD 6570 uses only 50 watt supplied by your PCIE slot.

But it is damn too expensive for purchasing from there, and it is older tech.

Check those R7 250, which use 65 watt and are good as well, with lower prices

Budget is about $150. All I want is a GPU that can run Garry's mod, Wow, LoL, on high settings and above 30 fps.

WOW would be your worst quality from all 3 games, Garry's mod, game from 2006 with GTX750TI will be your highest setting, ULTRA, if such exist, next would be LOL on HIGH, and final WOW, where you PC will have, most likely, minimum recommendations
By the way, you did not provide your CPU model and your RAM model, also, which OS you have and is it 32 bit or 64 bit, please do, some upgrades might be possible to increase quality of your games.
For now, this is the best card to fit in your PC and it will work on your power supply, because it draws power only from PCIE slot.
MSI N750ti-2GD5TLP GeForce GTX 750 Ti 2GB 128-Bit GDDR5 there is nothing better exist for now, which can fit in your PC.
However, considering that your CPU would be a bottleneck for this card, your appetites can be lower like
GTX 750, so you can spend the rest of money to improve your RAM and CPU. By the way, what are your preferences AMD Radeon or NVIDIA?

Since my concerns with WOW settings, these are the recommendations:

Minimum Requirements
Operating System Windows® XP / Windows Vista® with the latest service pack
Processor Intel® Core™ 2 Duo E6600 or AMD Phenom™ X3 8750
Video NVIDIA® GeForce® 8800 GT, ATI Radeon™ HD 4850, or Intel® HD Graphics 3000
Memory 2 GB RAM (1 GB Windows® XP)
Resolution 1024 x 768 minimum display resolution

Recommended Specifications
Operating System Windows® 7 64-bit/ Windows® 8 64-bit/ Windows® 10 64-bit with latest service pack
Processor (this is what you can not achieve) Intel® Core™ i5 2400, AMD FX™ 4100, or better
Video NVIDIA® GeForce® GTX 470, ATI Radeon™ HD 5870, or better
Memory 4 GB RAM
Resolution 1024 x 768 minimum display resolution

So your specs please.

My CPU is the Intel Core 2 Duo CPU E6750

The RAM I have is DDR2 2.50 GB

My OS is Windows 8 Pro 64 bit

Sorry if the info I gave you ism't helpful. I don't know a lot about hardware. But I do really want to learn. Also, you said the GTX 750 Ti would fit in my PC. We ARE talking about the desktop version of the Dell Optiplex 755 right?

By the way i'm also thinking about getting a grounding strap for when I put the GPU in my PC, do you recommend getting one? I heard that all you should do is just touch something metal to discharge the electricity in you every now and then while in the process. Also I do not have carpets.

[strike]Easy things first.
MSI GTX 750TI lower profile (in the link) has low profile brackets, which should assist you reducing height of your card PCI metal bracket, so that you can fit into the smaller case.[/strike]

Hold on, there is a problem with certain Optiplex motherboards, your included, regarding clearance of GPU, need more time, do not purchase the card unless you are good with a Dremel!:??:

That hour from las post was spent in frustration over the findings - now each Optiplex has to be treated differently because there are a few resistors near blue handle of PCIE slot, which create an obstacle to sit card (MSI) completely. Also, I found and partially investigated another issue with hard drive cage on top of the card.

Make story short, MSI GTX 750TI LP is excellent card, but fitting into certain Optiplexes becoming very difficult, special Dremel skills are required.

So, in order to fit this card into your case you have to use this

rbe6ohbigqfydhdg964o.jpg


And cut MSI GTX 750 TI Low Profile card like this

71r7DPeZOiL._SL256_.jpg


Also, you would have to trim hard drive holder (caddy), because MSI heatsing cover is a bit to high and prevents HDD caddy to fit in place (no pictures here:'().

Scared, me would be as well.

So, I went on searching for a substitute, found one, but here is the story.

This card manufacturer called Galaxy. Unfortunately over the period of 2014, Galaxy name seized to exist, apparently through some restructuring and a new name was born - Galax.
I believe they are using the same manufacturing facilities and GTX 700 series cards are the same from Galaxy times, however they only sold in USA through their website, I could not find any retailer yet with their cards.

Why I am talking about it, you may ask, look below, this is the simplest card to fit in your case and its fan cover seems to be lower than MSI

gtx750tiocslim2gb-bigger-2.jpg


Unfortunately, it can be purchased from them directly only

GALAX NVIDIA GeForce GTX 750 Ti OC Slim 2GB for $124.99
GALAX NVIDIA GeForce GTX 750 OC Slim 1GB for $94.99

In order for this card to fit over 2 resistors, look below near blue handle of PCIE slot

dell_optiplex_75_4ec1915f6b683.jpg


plastic fan cover has to be removed, confirmation

I have a Dell optiplex 745 sff - just bought and installed the following card which I'm pretty sure is the "best" possible upgrade choice...GTX 750Ti - it's low profile, single slot and doesn't require an additional power connector - been using it with original psu no prob. The only caveat is that there were 2 tall capacitors in the way of the heat sink on the card that prevented it from seating all the way into the slot. So I just removed what appears to be a cosmetic bracket over the fan and that gave the card enough room - everything has been working fine since installed

So, this is the only way now, unfortunately.

In the next post I will go over the rest of the components.

Edit. Just found better picture of your motherboard where you can easier see those 2 tall resistors

Now more difficult decision, processor.

Yours is just a bit above minimum for WOW, if you considering upgrading it those are the strongest supported by your PC:

3.00GHz Yorkfield Quad Core 3.00GHz, Q9650, 12MB
2.83GHz Yorkfield Quad Core 2.83GHz, Q9550, 12MB, 1333FSB, E0
2.66GHz Yorkfield Quad Core 2.66GHz, Q9400, 6MB, 1333FSB, R0
2.66GHz Kentsfield Quad Core 2.66GHz, Q6700, 8MB, 1066FSB, G0
2.40GHz Kentsfield Quad Core 2.40GHz, Q6600, 8MB, 1066FSB

Plus the rest, just in case

Intel Core 2 Duo E6850 3.0GHz, 4MB L2 cache, 1333MHz FSB
Intel Core 2 Duo E6750 2.66GHz, 4MB L2 cache, 1333MHz FSB
Intel Core 2 Duo E6550 2.33GHz, 4MB L2 cache, 1333MHz FSB

Intel Core 2 Duo E4600 2.4GHz, 2MB L2 cache, 800MHz FSB
Intel Core 2 Duo E4500 2.2GHz, 2MB L2 cache, 800MHz FSB
Intel Core 2 Duo E4400 2.0GHz, 2MB L2 cache, 800MHz FSB

Intel Core 2 Duo E2180 2.0GHz, 1MB L2 cache, 800MHz FSB
Intel Core 2 Duo E2160 1.8GHz, 1MB L2 cache, 800MHz FSB
Intel Core 2 Duo E2140 1.6GHz, 1MB L2 cache, 800MHz FSB

Intel Celeron 440 2.0GHz, 512K L2 cache, 800MHz FSB
Intel Celeron 430 2.0GHz, 512K L2 cache, 800MHz FSB

Q9550 from this list looks more promising, since it is almost twice cheaper on eBay than Q9650, which is just a bit stronger.
Processor to choose has parts numbers:
EU80569PJ073N is an OEM/tray microprocessor
AT80569PJ073N is an OEM/tray microprocessor in Halide free package
BX80569Q9550 is a boxed processor with fan and [strike]heatsink[/strike] (English version) (you can not use this heatsink)
BXC80569Q9550

If you decide to upgrade processor, let me know - it will involve one more purchase, most likely - CPU heatsink.

And finally you RAM/memory. 2.5GB is too litlle, you need at least 4GB, better 6GB and the best is 8GB, no more.

Do you know what is your RAM sticks are?
if not, get CPUZ, instal and go to memory tab, scroll through the slots to see individual info for each stick, they all should be same speed.
Can you please post here how many sticks each size you have and what is their speed, please do not run full CPUZ report, it is too long to read.

Your turn.

Thanks for the help man, really appreciate it. Now, due to my curiosity I managed to somehow damage one of my ram sticks. I opened up my PC and took out one of my RAM sticks and placed it back in (I think I pushed down too hard) when I tried to boot up the computer it was giving a series of beeps. I looked up it and figured out it had something to do with the memory. I proceeded to open up my computer again and repeated the process, it booted up normally. However, I checked my PC info and it says I only have 1.5gb of RAM now. Yeah I know, I screwed myself over. So I am going to buy more RAM specifically 2 of these.

http://www.amazon.com/gp/product/B005CPUPJY/ref=ox_sc_act_title_4?ie=UTF8&psc=1&smid=A3LKWIQ3PBTNT2

2 of these RAM sticks should work fine for my PC right?

Ok, lets turn to RAM now.

Have you checked with CPUZ your memory as I asked, why? I would try to save you money if possible, but not at expense of performance.

Looks like you found very cheap memory on Amazon, at this price I would encourage you to buy 4 sticks so you can have 8 GB.
As of now, it seems like you have unmatched pairs of RAM installed, from the service manual

When installed in pairs, DDR2 memory modules should be of matched memory size and speed. If the DDR2 memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.

If you install mixed pairs of PC2-5300 (DDR2 667-MHz) and PC2-6400 (DDR2 800-MHz) memory, the modules function at the speed of the slowest module installed.

This is a good picture to illustrate installation in pairs

Is your memory installed according to those rules?

Now you know about RAM installation rules, questions?

Are you considering CPU upgrade? If still undecided, I would recommend upgrade RAM first to 8 GB and check WOW game play, if not good, proceed to GPU, GALAX choice is the best for your money, unless you have a huge screen resolution, 1GB version is more than enough. If you think, it will cost you too much, I checked fitting in general for lower priced cards. So far I could not find GT740, which can fit, only GT730.
So, you have a choice, GALAZ GT750TI or PNY GT730, which is visually very skinny, there are GT740 cards almost the same, but their fan covers might be a problem, could they be removed, I really don't know, to find out will take enormous time.

So, just to clarify. I'm going to buy 2 of the RAM sticks I linked. As the picture says I put 1 stick in each white clip?

I would recommend 4 sticks, but is is up to you. Answer yes.

But what you have installed already, you said, you have 1.5GB of RAM left, what is it? 1GB + 512MB? If this is correct, it would decrease overall performance compare to extra 2 sticks of 512MB each
More reading material towards the middle of this post http://www.tomshardware.com/forum/302479-30-matched-pair

Basically, match your memory where you can, if all 4 sticks are the same, they will give you the most performance, if you have different sticks from 3 different manufacturers, motherboard will choose the slowest and run all memory at its speed.

I took out all my ram sticks and put em back together. I managed to get back my 2.5gb. However one of my sticks was unlabeled. But as far as I know, I have 1 gb stick and 1 512MB stick. I'm not so sure which the other one is.

Regarding the CPU. I was not aware that the CPU for the Dell Optiplex 755 Desktop was optional to upgrade.

I asked you above, you probably missed, to instal CPUZ to check your memory from software level, not just visually.
When installed, go first to Memory TAB and copy here:
Size:
Channels#: is it Dual?
DRAM Frequency:
Next go to SPD TAB and scroll through Memory Slot Selection and state info for each slot:
Module size:
Max Bandwidth:
Manufacturer:
Part Number:

For Timing table there are too much info, so just take a look there, are they all the same, or at least 2 x 1GB sticks are the same or not, also pay attention at voltage.
Report ASAP, if you have all different memory sticks, no matter what you upgrade, system will run at the slowest existing (slowest stick) speed.



Officially Dell states that CPU upgrade would void warranty and, therefore, is not advisable or not recommended. However, when asked directly, certain answers can be obtained.
I don't think you have to worry about warranty, am I right?

Size: 2560 MBytes
Channels#: It is Dual
DRAM Frequency: 332.1 MHz it changes to 332.5 MHz but for most of the time its 332.1 MHz

Slot #1
Module size: 1024
Max Bandwidth: PC2-5300 (333 MHz)
Manufacturer: Samsung
Part Number: M3 78T2863RZS-CE6

Slot #2
Module size: 1024
Max Bandwidth: PC2-5300 (333 MHz)
Manufacturer: Epida
Part Number: EBE10LE8ACFA-6E-E

Slot #3
Module size: 512 MBytes
Max Bandwidth: PC2-6400 (400 MHz)
Manufacturer: Samsung
Part Number: M3 78T6464QZ3-CF7

I took a look at the Timings Table. The 2 x 1GB sticks are the same. The 512 MB was different. The voltage for all 3 were the same.

So, you're saying when I get my new RAM sticks and install them if I have one of the old 1Gb sticks installed it will run at the 1GB stick's speed? Also I am getting 3 sticks instead of 2.

I do not have to worry about warranty.

All 3 sticks are different, too bad.

You are getting PC2-6400 (400 MHz), but you have PC2-5300 (333 MHz) in 2 sticks, you PC will run at 667 MHz FSB, maximum speed of your PC is 800 FSB, in order to achieve this you must have only PC2-6400 (400 MHz) memory, that is why I was advising for you to get 4 sticks!
Or you choose to save 512 MB stick?

I was thinking of getting these RAM sticks instead. Do you know if these will work with my motherboard?

Your PC compatible with DDR2, that Crucial is DDR3 - it would not work and you risk braking either memory modules or motherboard memory slots

While they share the same number of pins, they are notched differently so that they won't fit. IF you forced them in and tried it, it will kill the memory. There is a voltage difference as well.

This will work, but why you don't want to get your first choice http://www.amazon.com/Dell-Certified-OptiPlex-SNPYG410C-A2149880/dp/B005CPUPJY/ref=sr_1_1?ie=UTF8&qid=1439501836&sr=8-1&keywords=optiplex+755+pc+6400
Your previous choice http://www.amazon.com/Dell-Certified-OptiPlex-SNPYG410C-A2149880/dp/B005CPUPJY/ref=sr_1_1?ie=UTF8&qid=1439501836&sr=8-1&keywords=optiplex+755+pc+6400 was faster, PC 6400 800Mhz, a bit more expensive for 4 sticks (making 8GB), I know, but faster..
Both choices, you first one and your last one are compatible, with last one been slower.
