Is there any benifits of a 7950GX2 over two 7900GTX EGS running in SLI besides being able to run Quad and just useing one slot,Can you do more with two 7900GTX EGS running in SLI over the single 7950GX2.I know if you were just buying a card the 7950GX2 would be the cheapest way to go ,but in my case the cheapest way to go is a stepup with Evga.

2x7900GTX has more juice cause of the higher clocks..so yes it will have a advantage. Ontop of that the cooler on the GTX work great and dont even need custom heatsinks to cool it down..

Only down side...too many 7900 series are running arround which are faulty and simply not worth the headache/trouble..i myself went 7900GTX first..sadly 2 brand new cards out of the box crap out..and i just went for the 7950 instead..there was x1900 then but i decided to go with the 7950 and pay the extra 100AU instead..so with that in mind..i would go the GX2..if your guranteed problem free cards (which i was told as well and turned out to be crap) then go for the GTX...it will cost u alot more to setup sli on the GTX than setting up a single GX2..while QUAD SLI when working will give you more perfermance for a extra bit of $$..

On the other hand..some people have o/c the gx2 to pretty high levels....only draw back on the GX2 is the heat management..but jeez..would you really wanna play the devils advocate with this much money and hardware..i really wouldn't recommend a 7900 series to anyone..just look at the posts arround..when i made a post about it before i got the gtx myself..everyones like "Dont worry it will be fine" " Its ok only a few people have this problem"..and volla..2 brand new cards..out of the box..crapped out..and the list goes on..not worth the headache..i lost alot of time/money trying to get it sorted out..

I'll echo K007's words. Two 7900GTX's in SLi will outperform a single 7950GX2 all day and all night. The GTX's have had more than a fair share of issues, but they were supposed to have undergone an overhaul of new memory chips to fix the problems. If you're going with eVGA, then you might be okay. They're well aware of the issues with the cards and will work with you.

There's roughly a 15-20% performance increase in GTX SLi from a single GX2.

I agree, gtx sli will always be faster but you can close the gap by OC'ing(the two GX2's i've tried have been amazing oc'ers). For price/performance the 7950 comes out on top no doubt. I see the eVGA for $499 at newegg all the time which is much cheaper than 2x gtx's

For unsupported Quad SLI games the 7900GTX SLI will surely win.
if you are not planning for Quad though .. a single 7950GX2 is better price-wise.

Yep GX2 is very good in the $ Value department..100AU more compared to the GTX..it is a tempting choice vs the x1900 at that time but it was a easy choice to go GX2 over the x1900 cause of the price..

The 7900GTXs of course have higher power draw as well.

G80 is right around the corner, why go with a 7900-series card in the first place unless you have the money to burn?

Ths is coming from a Quad-SLI owner, mind you. I'll be returning my Quad-SLI to Newegg shortly, in anticipation of the G80.

Hopefully the G80 gets released this month and not November-December.

Gtx Sli Ftw! Specs are pretty identical, but the GTX has higher clockspeeds.

Has anyone tried to get 650/800 on there GX2 :O?..i bet then it will be equal to the GTX.

You should just keep your 7900GT SLi and wait for G80..

That must be the be the I'll borrow the top end hardware at the expense of Newegg, Evga, Nvidia and in the end every consumer plan.:thumbdwn:
Sorry but I had to say it.

One thing that you should keep in mind when comparing these two setups is that when using a 7900gtx sli setup you will more than likely only have one PCI slot available to you. With the 7950 gx2, while losing some performance, you will gain by having all or almost all of your PCI slots available to you. This helps if you plan on adding an x-fi/PPU/Nic or any other type of card out there. Plus like otherís above have said, if G80 is right around the corner, it is best to wait a little bit longer, who knows what kind of cooling they have designed for the new cards, maybe single slot gtx cards this time around.

Anyway let us know which way you go in your build.

IF there is room for the GTX to spread the GTX will have a pretty big gap..some sli reviews with the GX2 sitting shows some pretty big gaps..but there are downsides and upsides to both..I am sure nvidia cauld have done a 650/800 if they wanted to but then that would kill the 7900GTX..

My XFX XXX GX2 comes stock clocked at 570/1550, should be pretty close to 7900GTX SLi performance for less money. 7900GTXs are at 650/1600, 7900 GTs 500/1200. As you can see the XXX makes up 50% of the clockspeed difference and almost all of the bandwidth.

Well yes, a single 7950GX2 is definetely a better deal, but the 7900GTX SLI would be slightly faster.

How does the XFX 570/1750 card compare to GTX SLI?

I have a Evga 7900GTX EGS just laying around and it is good and give no problems and it overclocks alright 720/1850 but I not planning on overclocking ,I just have two Evga 7900GT Signature Series and my 90 day step-up was running out so I thought about going to a 7950GX2 but that was going to cost me over $200 to step-up and the 7900GTX EGS was just $100 and since I have another just laying around I thought I might as well go to two 7900GTX EGS since the bugs are suppose to be worked out,and I was'nt really interested in quad because the highest resolution I run is 1600x1200 and I did'nt think it would really be worth going to a quad at that resolution IMO.

Nvidia had a single slot GTX this gen, I guess the 7800GTX HSF wasnt up to par for 7900 seris.

Tough to say, I don't think I've seen them directly compared. However, some reviews compared them to 512 7800GTXs, which were clocked at 550/1700, and they did quite well:
