Greetings!
Before I begin the forthcoming wall of text regarding the topic at hand, I just wanted to commend the sponsors of this board for providing such a great resource. There is so much useful information available here and the members really make all the difference in helping people with their questions (from what I've seen; I joined up simply because I've been able to find out so much about so many different subjects here). Anyhow, just wanted to say - excellent work!
So, here's my situation:
Finances are extra tight in my household as of late and I know that the true solution to all my computer woes would be to simply buy or build a new computer. Unfortunately - because of funding - this option is simply out of reach at the moment. So what I am stuck with is an old Dell Dimension 4550 that someone gave to me about two or three years ago as a way of saying thanks for helping with a move to a new apartment. As those of you who know even a little about computers are aware, this is far from a gaming rig and options for improving this dilemma are extremely limited. I've researched quite a bit about this system, so I'm being honest with myself and not expecting any miracles. However, I do think there are few upgrades I could perform that will fall within a quite reasonable budget and may be worth trouble; that is - if I could kindly ask you folks for a little advice on whether or not my suppositions are warranted or not. Bear with me - I'm very new to A LOT of this stuff, and as I said, I'm not expecting any miracles as far as performance if concerned with this very archaic and limited system. Just looking to breathe a little bit of extra life into a dying system. That said, here goes:
For starters, here's the data sheet for my current system:
http://support.dell.com/support/edocs/systems/dim4550/specs.htm
My mobo:
http://www.epinions.com/specs/DELL_J0592_Motherboard
Simple overview of my CURRENT system configuration:
Dell Dimension 4550
CPU: Intel Pentium 4 2.53 GHz (non-HT enabled)
RAM: 2 GB DDR
GPU: EVGA e-Geforce 6200 PCI 256MB
OS: Windows XP Professional SP 3
Hard Drives: 2 Hard Drives; No RAID setup options available - both are identical WD 320 GB 7200 RPM 8MB Cache ATA-100 EIDE HDD's
Monitor: 22-Inch Insignia 720p 60Hz LCD TV
Currently, the system I have here is equipped with the Pentium 4 2.53 GHz processor (non-HT). The best price I was able to find for the maximum processor upgrade available for my board (socket 478, 533 MHz max FSB, Intel i845PE mobo) was this Pentium 4 3.06 GHz HT enabled cpu, socket 478, 533 MHz FSB for about $29 USD including shipping costs:
https://www.starmicroinc.net/cgi/commerce.cgi?preadd=action&key=IP306C5
Here are the specs for this cpu from the manufacturer's site:
http://ark.intel.com/Product.aspx?id=27499
I'm aware that the jump from the 2.53 GHz non-HT to the 3.06 GHz HT would probably be rather insignificant; and that the Hyper-Threading feature of the latter would only yield 2 logical threads, but still only be a single-core processor. The only real place I could see this making a tiny difference is in multitasking (not that I do a lot of intensive multitasking on this system to begin with). I do use programs like Photoshop CS 5 and Flash, but only rarely (I'm in online college courses for Animation), as necessary. Nothing too intense. The reason for the CPU upgrade would really be out of sheer curiosity and also because I'm looking to throw a different GPU/graphics card in the tower as well.
Because it's a wonderful Dell machine, I have absolutely ZERO overclocking options available to me (trust me - I've scoured around looking for ANYTHING that will allow me to even alter the slightest thing. No dice, whatsoever). The only thing that I was able to do was use a Windows GUI-based program called MemSet to change the RAM timings. That's it.
My current GPU is - hope you're sitting down... An EVGA e-Geforce 6200 256MB PCI card. Yes, I said it: PCI (NOT PCI-e). (-=laughing=-). Back when I bought the thing, I knew nothing about video cards (not that I know anything more about 'em now), and it was the only PCI card I could find in a local Circuit City at the time. Anyhow, at stock it had a core clock of 280 MHz, no shader clock that I was aware of, and I believe a 425 MHZ memory clock. I was finally able to find a way to overclock this GPU by flashing a custom bios over the board. It's now at a stable OC of 352 MHz Core/ 730 MHZ Memory. Still, this thing was never meant to be a gaming card to begin with... and as I've only recently learned (by reading posts on this board nonetheless), it's a a godawful PCI card. Luckily, it's only sharing the bus bandwidth with my PCI WiFi adapter card. I've also installed a TinyXP 32-bit Operating System (I can only do 36-bit with this rig, no 64-bit even if I upgraded the processor to the one mentioned above). By the way, although I realize that TinyXP is not an official, legal build, my product key is; so that part is legit. Anyway, these minor tweaks have allowed me to run DOOM 3 with Ultra Quality settings enabled and everything but AA @ 1024 x 768 resolution with some very playable framerates (cannot confirm exactly how many FPS I'm getting as I haven't tested it; but animations and movement are usually very crisp and smooth. If I had to guess I'd say the 25-40 fps range, because it is extremely playable as I've suggested). Half-Life 2 (which I know could probably run on a calculator powered by a hamster on a spinning wheel because that Source engine is just so highly optimized for even older systems) actually looks pretty stunning. I've gotten Far Cry 1 to run pretty smoothly at 1024 x 768 with most of the settings on High (no AA for any game though... that's where things really slow down). I know I'm YEARS behind what everyone else is enjoying nowadays, but unfortunately, this little puppy is all I've got for right now.
Yet, I still can't help but feel like I could get a least a *little* bit more out of this system (even though the bottom line is that it is - ultimately - utter crap).
So, I noticed that I do, however, have a completely free AGP slot... Only thing is that I'm limited because it's an AGP 4x slot.
I was able to find a used Geforce 6800 GT 256mb AGP 8x card going for $15 including shipping costs on eBay. From what I've read up on this model, it will be fine and downclock to accomodate a 4x AGP bus. The problem I see, is that the manufacturer recommends a 350W PSU for this card. My system is only equipped with a 250W PSU. I really don't want to have to go through the expense of getting a new PSU if I don't have to. Plus, it's a Dell. I'm pretty sure that if it's even possible to change out the PSU at all, I'm gonna have a difficult time tracking down a higher wattage PSU that'll be compatible.
Question #1: I'm wondering - If the card is running in AGP 4x "mode", will this consume any less power?
Now I know there is the worry of the bottlenecking with a card like that in the system. Apparently, my mobo will only go as high as 2 GB DDR RAM (which I have in there already - one 1GB stick @PC3200, the other a 1GB PC2700). So, I'm stuck there. I know I could replace the second PC2700 stick with an additional PC3200 one to complement the other, but - again - if it isn't completely necessary, I won't bother and just save the cash.
Question #2: Will the upgrade from the P4 2.53 GHz (non-HT) processor to the P4 3.06 GHz (HT-enabled) processor help alleviate concerns a little bit where bottlenecking would be concerned running the Geforce 6800 GT AGP 8x card @ AGP 4x bus speeds?
I know it's quite a longshot, but I'm being real with myself and knowing I can't expect to play games like Crysis or even Call of Duty 4: Modern Warfare with reasonable settings, even with the upgrade. I'm just looking to play the 2006 and prior games a little bit better (i.e. Far Cry 1, DOOM 3, QUAKE 4, HALF-LIFE 2). And I figured, if for just $45 USD I can squeeze a little bit better performance out of an obsolete and ancient rig, that won't hurt my wallet too much and may be worth the couple bucks. Considering I didn't pay anything for the system to begin with (with the exception of the Geforce 6200 card I chucked in there), $45 spent won't be such a lofty investment until I can get the financing together to get a REAL computer. I just would like some confirmation if it is achievable from a technical standpoint.
Some other options I considered:
This CPU:
Intel Pentium 4 3.2GHz 800MHz 1MB Socket 478 CPU
http://computerpartsdirect.us/intel...0.html?zenid=0144ae363a0e114143532fe590147a02
I would do this one, but I'm 99.99% sure my mobo wouldn't accept it. Even though it's a socket 478 (Prescott? Northwood?), it's got an 800 MHz FSB rating. I'm not certain that my Northwood mobo @ 533 MHz FSB would even be compatible. Still, if it could work, it'd be better to go to 3.2 GHz and a 1mb cache.
These GPU's/Graphics Cards (Not that my system could take advantage of any of these):
EVGA NVIDIA GeForce 7800 GS AGP
http://cgi.ebay.com/ws/eBayISAPI.dl...90+&clk_rvr_id=241819323528&item=320716412390
Double what I would pay for the 6800 GT AGP, but from what I understand these 7800 GS AGP's were meant to replace the former mentioned card.
Gainward Bliss 7800 GS 512 MB AGP

Thanks for bearing with me and sitting through this promised "wall of text" for such a trivial system. Trust that any and all help would be greatly appreciated by this hopeful gamer in a (hopefully, only temporary) financial pickle. Thanks in advance and take care all!
