question is...

I have my heart set on a pair of EVGA 7900GT Signature Series cards running in SLI....

Both cards would be OC'd at 670/1900 with 256 megs of RAM each.

Very fast yes....

I believe this would be either on par or perhaps better than a single 7950GX2.

Now I hate to say it but...convince me...


1 gig Vs a pair of higher clocked 7900GTs....

I'm also hearing that the 7950GX2 doesn't run like a set of SLI'd cards....but rather a single HUGE multiple GPU card.

If this is true then I can deffinitly see the higher potential with a 7950GX2....

I'm stuck.

Many people have suggested I just go with another 7900GT SS to complete my SLI configuration...

some have mentioned I step up to a 7950GX2.

crossroads.

I'd say go for a 7950GX2 if you have the proper mobo for it .. one card will have less troubles than 2 any day (if we can call it one anyway heh)

I have an Asus A8N32-SLI or something rather...32x mobo

Well, I have two 7900 GTX Superclocked cards, which right now are still on top, even putperforming the 7950s. I already stepped-up my cards for two 7950's. The real big gamble here is Quad SLI, it's the only reason I went ahead and swapped. Nvidia just announced at Computex that Quad SLI support will not be available officially unti lthe end of summer. There's also some benhcmarks showing the 7900 GT SLI getting beat by the 7950, and even beating the o/c 7900 cards in SLI. The benchmarks went back and forth, and are pretty much neck to neck. Personally, if were you wait out your step-up as long as possible since Quad is a tad bit away, plus there's the chance that eVGA will release o/c 7950's soon which you could def step-up too. It really all comes down to patience, if you had 7900 GTX SC card's I'd say stay, but with the SS I'd go ahead and step-up expecially since you get ahead of the line for those SS cards. Check out the 7900 GT SLI O/C vs 7950 GX2 here (http://www.pcper.com/article.php?aid=256)

well I'm thinking this: order my other 7900GT SS and clock it 670/1900.

run SLI 7900GTs SS @ 670/1900 then step up each card towards the end of the 90 day to the OC'd version of the EVGA 7950s....

should be a SAFE idea yea?

Sounds good, but how old is your current 7900 GT SS, you only get 90 days. If it's still new and you have plenty of time then it sounds like the best choice to make, plus 90 days just makes summers end get closer to the release of Quad SLI support :p

I have only had the SS card for about 1 week now.

so yes, pretty new.

Still a hard call, the GX2 still beats the 7900 GT OC SLI off and on. Even if you buy a new 7900 GT and step up, you'll evnetually be paying the same price after the 7900 SS purchase and difference pay from the 7950 step-up. Sounds like it'd be easier and cheaper to just get a 7950 GX2.

well consider this:

I buy the other 7900GT SS card...

By the time I want to stepup the EVGA OC'd versions of the 7950GX2 will be out...even perhaps a SS version of the 7950GX2 will be out...

I think I will still yeild some amazing results with a 670/1900 in SLI


I mention an EVGA Signature Series 7950GX2 becuase think of it...all they are is 2 7900GT's put together. Now why couldn't EVGA put 2 7900GT SS cards together to make an SS 7950GX2?

hrm..........................

The best option is to wait out the 90 days. And I beleive some of those benchmarks were with 7900 GT SLI using 7900 GTX SC speeds.

do you have a source saying that the 7900GT SLI setup were using GTX SC speeds?

No but it's on par with a stock 7900 GTX, when o/c to the 7900 SC speeds it outperforms the 7900 GTX stock almost always. You can tell by the 3dmark scores and benchmark results from the 7900 GT SS vs the 7900 GTX stock and SC cards.

I had 2 7900 gts oc'd close to the specs you are saying with the Signature Series. And my optimal OC'd 7950 GX2 is simply blowing away those cards.

Get a 7950 GX2! (nana2) You will not be disappointed. The extra memory seems to have made things much smoother.

It's true, I just searched other forums and found users who have 7900 GT SS and even further o/c them, still the 7950 is blowing them away, especially o/c.

I think the 7950 is more valuable overall because of the 512MB texture memory.

can you show the URL or source of where you are finding the 7950GX2 vs. the 7900GT SS OC'd cards?

I'd like to see for myself.

Yep. IMO, theres no contest here. With 512Mb of graphics memory you will get significantly smoother gameplay when you really start pushing card, especially with the next generation of games.

Get the 7950GX2.

Can someone explain to me how this is working....


7950GX2 is basicaly NOT seen as 2 video cards right....

but more seen by XP and games alike as 1 GIANT 1 gig Dual GPU card correct?

jAkUp

Yup, to be honost, the 7900GT SLI and 7950 are so similar in performance, it comes down to texture memory on the card.

Not to mention, the 7950's are pretty good overclockers.

Unfortunately no :(

2 GPU's. Each GPU writes to the framebuffer, so you only get 512MB texture data.

You will also see 2 GPU's in device manager... I see 4!!

The 1GB is nothing more than marketing. Technically it has 1GB of memory on the "sandwich" but only 512MB is usable.... but in all honosty that is fine for now because there is not a single game on the market that uses over 512MB of texture memory.

what kind of overclocking are we seeing on these cards? and is it making a bid enough difference.

another reason why I would want to wait is becuase EVGA will probably release an OC'd version....or better yet....a signature series version!

How come in the Nvidia properties it says it using 1GB though? Cuz my card is showing 1GB in the driver settings not the SLI like 512. The reason I was thinking it is using 1 GB is that in my system acts like its one card that just happens to have to have 2 GPUS bolted to it.:D

Unless you like running SLi AA I can't see a reason for dual card configs at 1280x and below. A single 7900 GTX or even OCed 7900 GT is fine. ECS has some GTs coming out with 512 memory that should be nice if they are priced right. If you game 1600x and up you should definitely look at a 7950 GX2, especially if you used combined AA|AF. There is always the option for quad SLi down the road as well.

From all the reviews it looks like SLI AA scales very well but game support is iffy at best. If you like the eye candy like NV have said the quad is probably the way to go.

I wonder if like Dual core CPU`s needing games to use threads to use both cores there is a programming trick that the develpoer must do in order to enbale better use of a quad system. its strange how only really fear gets a performace boost and other games dont. I bet fear is very heavly optimised with all the tweaks from the GPU makers just to make it run, so (maby) its already optimised for multi GPU system. Maby other games that ran fine on most peoples rigs did not get the extra perforamce tweakage due to not needing it.

if this is the case then you can bet crysis and the rest of the NG titles will be optimised like this.

if running at 8x or 16x AA is your thing then go with GX2 and maby get another later, else probably get a 7900gtx save the cash and invest in a new MoBo / Ram / Conroe. how mch are you going to be gaming during the summer months when itsw boiling hot outside??

Conroe is probably gonna cost $$$ as it taking the performace crown from AMD and intel like all other blue chip makers know that the hardcore / performace gamer will pay what ever you ask for the latest and greatest.


The GX2 probably isnt worth the cash but if you want to play the current gen of games then get one else its probably wise to hold off for a bit.
