690 vs 7070 CF

[brunokill]

So I was thinking about getting the 7970 in CF but I then thought that it would make my case hotter, which will result in hotter cpu ect so I looked at the 690. If I buy the 690 I will use a 650w power supply where as if I get the 7970 CF I would have to get a 850w power supply. Overall the 690 is more expensive but is the decrease in temperature worth it? Also I'm planning on overclocking, which card is better to overclock with?

 

[ultrakill]

the 690 gtx is the fastest gpu out there

but for the gtx 690 you need more power a650w psu is not enough

you will need minimum a 900w

and for overclocking i dont know why do you need to overclock a gtx690( a beast)

but yes it is possible i would sugest you to go with the gtx 690

is is expensiver but its the best

GOOD LUCK

Where did you come up with that 900w minimum requirement for a single 690? The 690 draws a lot less power than two 7970's and less than two 680's as well.

Where did you get 900w for the gtx 690?

Taken right from nvidia's site its 650w minimum. The gpu only uses 300w of power anyways. I would get a 750w-850w PSU for the gtx 690 if you want to be safe and/or overclock it.

Regardless, I would go with the gtx 690 over 2 7970's simply because of power and heat reasons. One card is always easier to put in/figure out than 2 cards anyways.

For information's sake though, two 7970's overclocked will be more powerful than a single 690 overclocked. However, if you go by recommended power supply ratings, getting 2 7970's will necessitate a 1000w psu (probably 900w though).

a gtx680 needs 550w

and you psu is not just for youre gpu there are other components in you pc who need power

and even if 900w is a little bit more better to have more power than less

How little do you think a 7970 needs? The 7970 asks for a 600w PSU.

Anyways, look at this:

 

[brunokill]

So which one should I get?

yes minimum 600w

but you need a good 600w psu a good brand : CORSAIR, COOLER MASTER, ANTEC XFX... ETC

I have a GTX 690 and only need a 750W PSU, my other components are an x58 system, overclocked i7 920 (to 3.99), 4 HDDs, a PCIe SSD.

General gaming and benchmarking (Heaven, 3DMark 2011) have no detremental effect on my systems stability. Bear in mind I have older architecture that requires more power than Sandy/Ivy.

The critical point is to make certain you have a good PSU - and one that covers your systems demands, including any overclocking. The one I use is a BeQuiet 750W modular.

I don't think you'll be disappointed in a 690 😉 but don't get one unless you plan on taxing it - now - or in the near future (e.g. triple screen, or 1600p).....it'd be a bit of a waste of money otherwise. +1 (as another option) - as bystander said below - 670 sli is not too far behind and will save a fair bit of money. There are various advantages in the 690 single card design/impact on the system; how significant these are depends on your circumstances (e.g. do you need to save space, power, etc).

Overclocking is very simple with a 680/690 - use EVGA Precision X (works with non EVGA gpu's also) this link gives you all you need to know....

Personally, I'd go 670 SLI, or 690. They have been shown to have less microstuttering issues. 670 SLI would save you a lot of money.

yes minimum 600w

Um no. 600w is for any brand. I guess you are one of those people that get a 1000w psu for a single card config.

Not all the brands give the wattage they say they give.

Just dragging the conversation back on track, what is this setup going to be used for? There are a lot of different scenarios that would result in completely different answers to your questions.

the 7970 CF set up would be better. if you are concerned about the case temps, well what kind of airflow do you have and would a fan or two resolve any of your concerns?

now, as far as any FUD about what wattage PSU you would need; it depends on the rest of the specs of your rig. generally an intel set up would be fine with a 750 watt PSU and an AMD set up with a 850 watt. as far as any "popular wisdom" that a PSU can't be too big; well thats just ignorant.

PSUs take a big nosedive in efficiency when below 20% of its rated load; about 5%-7%. so when your rig is idling, which it does most of the time, the money you spent buying an 80+ or bronze rated PSU (if not better) is wasted as it gets about 76%. also when a PSU is inefficient it get hot so therefore you will be aging the capacitors and decreasing the life of that nice spiffy PSU.

a PSU ought to fit like a glove; an idle of over 20% and full load under/~80% of continuous maximum.

If you wait for the 8990 it is supposed to be faster than the 690

 

[unksol]

The 7970s will be faster. And better for multi monitor/high res. Really who cares about power usage for this kind of setup? Id take 670 or 680 SLI before a 690 too, but the 7970s still win

 

[griptwister]

How much more awesomeness do you need? A GTX 690 is amazing!!!

yes two 7970-s are better and faster

but 2 gpu-s means 2 more problems

there are many people who have problems with crossfire or sli

and if you are not technically minded you are going to have a bad time

so i think it would be better to have 1 singlel powerful gpu

then 2 less powerful gpu

So a GTX 690 isn't SLI? 😗

 

[ultrakill]

So a GTX 690 isn't SLI? 😗

technically yes cuz its made of 2 paired gtx 680

but it wont make problems like crosfire or sli

cuz its factory paired and they know how to do it

 

[ultrakill]

not at all the same the gtx 690 is superior

and many many many people complain about the problems that they have with the sli gtx 680

so as i said theoretically they are the same but in practice i would go with the gtx 690 (less problems)

 

[RussK1]

hahahahahahaha

Wow

Some people are so gullible. It's SLI on a stick buddy and it has the exact same positives and negatives as SLI. The ONLY difference between that and 680 SLI is that it comes on one PCB instead of two and it's clocked a little slower. Being on a single card just means that it takes up physically less space - that's it. It doesn't alleviate ANY of the drawbacks common to multi-GPU setups.

Yeah wow... SLI is SLI no matter how it's sliced.

Surprised nobody has mentioned the 7990 yet being it beats the 690. The Asus Ares II is the cats meow if money is not a problem +/- $1,500

because 1500$ i mean put 300$ more and you can get 2 gtx 690

Has it occured to you that perhaps the reason you don't see as many complaints about the 690 might be because only a fraction of people have a 690?
