I just got my EVGA 7900GT Signature series card (BTW...very kick ass) I have this card running OC'd at 670/1800...which by all means is very forgiving indeed.

so...............I'm either thinking of picking up another EVGA 7900GT sig. and doing the same OC...(i've heard of overall good consistancy with these cards when it comes to OCing) or going with of course the new 7950GX2 and selling off the signature series..


By the way things are looking....getting another sig. series and running SLI may be better. If able to do 670/1800 in SLI then I think that would still be a better performance increase then say a single 7950GX2.

The only thing I'd be missing is the additional 512 megs of RAM. Which is kind of a bummer, but I do say that the 670/1800 OC deffinitly makes up for that.


what do you think I should do?

I think the 7950 GX2 with the extra RAM is worth it. No matter how fast your card is, if you run out of ram, youre going to be swapping from system memory over the PCI-E bus. You dont want that at all, and with a faster setup, youre more likely to crank the settings which will probably make the memory swapping worse.

I dont think a super fast 256mb graphics setup is a good idea at all.

If its stable keep your current configuration, and buy another Sig card.
Those cards rock and have excellent support from EVGA you always have stepup for later.
Also think about letting the dust settle from the 7950 and driver to mature beside you get priority on the stepup program.
I just RMA my HIS x1900xt which is way I have a 7950 in my sig and paid just 100 bucks in difference so for me it worked. just my 2cents.

There's no way a 7900GT SLi--OC'd or not--is going to outpower a 7950GX2. Keep in mind that you should be able to OC the GX2 close to GTX speeds w/ proper cooling. The XFX Xtreme edition GX2 comes close to a 7900GTX SLi setup as it is.

And as someone already said, there's the memory issue... and the fact that you could always add a 2nd GX2, etc...

true true. deffinitly seems obvious now.

However, the GX2 is only 512mb effective, but still, if you can afford it, I'd go GX2 all the way.

im not sure on your reasoning...2 7900gts at 670/1800 is over 7900GTX SLI speed, which is faster always than a 7950GX2...

You have 256mb of memory, instead of 512 though

IMO if you play at resolutions of 1600x and up with AA|AF active definitely get the 7950 GX2. ECS supposed to have 7900 GTs with zalman like coolers and 512mb ram coming out later. Those should be very nice depending on price.

Another added bonus with the 7950 GX2 would be quad SLi, you would have that as an optional upgrade path for the future.

well I hope EVGA will let me Stepup to a GX2. Would suck if I can only step up to the 7900GTX. that would be lame.

They are allowing it for step-up, but the queue at the moment is very high, everyone wants these cards.

well I get FRONT OF THE LINE STEPUP becuaes i have the Signatuer Series. One of the nice perks you get when you buy the SS card.

the only question I have is if I'm allowed to stepup to the GX2 rather than having to step up to the 7900GTX.

not sure if its an option for me...

the way I see it...

7900 SS - 7900GTX - 7900GTX superclocked - 7950GX2.

I would have to jump twice to get to the 7950GX2! So hopefully EVGA will simply let me pay the difference and just stepup to the GX2.

You can step up to almost any card you want, including the 7950 GX2 :D

ah, well thanks for the answer...evga is lagging on a response to me...their emailing sux.

It would seem that I am at a fork in the road....

go with 1 GX2

or 2 7900GT SS cards...both oc'd to 670/1900

that would be pretty impressive...

only major difference is:

GX2 = 1 gig of RAM

SLI 7900GT SS - 512

also:

GX2 = 500/1200

7900GT SS oc'd = 670/1900

wow....

what to do...what to do...

Well again it all comes down to 256MB versus 512MB (note that's the effective memory you can use, memory isn't shared in SLI, so having two 256MB cards still means you only have 256MB video memory available to games. The 7950 has this same limitation, it only has 512MB effective memory).

The question is does 256MB versus 512MB matter. It's a tough call. There hasn't really been any in depth reporting on how much video memory games are using. Theorhetically having lower video memory should cause some stuttering due to texture swapping or vertex data swapping, but I'm not convinced there's any game that uses that much memory. All the game's out there that have stuttering problems supposedly due to video memory seem to have just as many stutters on 512MB cards as they do on 256MB cards.

If you can step up to the 7950GX2 then you should definitely go for that, no brainer. However, if you can't, then it might be more worthwhile to go for the second 7900GT.

First you need to register your card on evga.com, once that's done go to support on their site, then to step-up. Simply put in what you paid for the cards, and what new card you want. It's that easy.

I agree. I remember when I had my 7800GTX 512 and was playing BF2.....on all high settings at 1600x1200. The 7800GTX 512 was quite the beast and I was able to get about 60+ fps steady.

the 7900GT SS has roughly the same feel to it. I do get about 60+ FPS but there is the occasional drop in the frames.

It is deffinitly hard to determin a lower clock speed for a bigger amount of RAM.... or high clock speed for a lower amount of RAM.

I'm not sure which is more important and...not sure if games are truly utilizing the full amount of RAM...be in 256 or 512.

The pressure is on me as well. My stepup ends in about 2 weeks, do you keep your faster 7900 GTX SC cards? Or trade them in for a free swap at two 7950's which have lower speeds? It's basically all a big gamble for Quad SLI, but right now it's a risk I'm willing to make and the decision that I feel is best. I overpaid for my 7900's and while it was a nightmare at the time, overpaying for them is giving me a shot at a free swap. It'll be awhile before the step ups go through so I still have time to change my mind.

I can tell you guys one thing. I don't have this card optimized yet, but already I can tell it's more stable than my 7900GTX was. Not a single artifact or freeze or stutter in any game so far. Rock solid *knock on wood*

I'm running Oblivion at a consistent 60+FPS on the outdoor environments at 1680 resolution w/ 16x Anisotropic and 4xAA enabled, all in-game graphics maxed.

Just got through running a 13,100 on 3dmark05 on stock speeds, 500/600. Gonna hook up the Sunon fans I bought next for some decent cooling and then we're off to overclock in a bit. I don't know if I can hit 14k but I'm betting I can come close. Funny thing is 3dM05 is a lot more CPU dependant than 3dMark06. I saw much better gains w/ 3dMark06. I'm right at 8,000 now, and I ran it w/ my GTX stock at 5950. W/ a decent overclock/cooling, I'm betting 9k is reachable in 3dM06, and that would make me happy since it's about what stock GTX's in SLi run.

The thing you really notice about this beast is that it pushes out more GPU power than your CPU can handle. It's like grandma behind the wheel of a Ferrari F50. My CPU just can't keep up.

Ya I haven't heard of a single user yet to have complained about artifacting or freezing, that was the prime reason Nvidia toned down the speeds from the 7900's. And 9000+ is reachable, kwynjunk is about to breach the 9000 mark. I heard that these cards do push out some crazy power and can buckle down the cpu, I'm really hoping this isn't an issue with Quad SLI and my cpu. Seeing how everyones testing out 3DMArk, how about some HL2 and CSS fps averages?

Haven't tested HL2 yet, but I was playing FEAR w/ 4xAA, 16xAF, all settings maxed and my frame rate never drops below 65 at 1680 res. Vertical sync's not working for me, though--is there some setting I'm missing? I've tried enabling it in-game and on my graphics panel and neither one seems to stick.

I know it's not working because I can see screen-tearing and my frames were shooting up to 140fps in some places on FEAR. :)

Which rendering mode should I be running in? SFR, AFR, or AFR2? I'm new at all this SLi stuff...

Odd because I'm using the latest official forceware drivers and I too cannot seem to get Vsync to work correctly on my 7900's. I haven't tried the new drivers with the control panel change, I just set mine for either multi gpu rendering or sli antialiasing. Haven't had to create a custom profile yet for any games they've all worked great.

Sounds like a driver issue, then. How could they miss something like that? (pirate)

ahhhhhhhhhhhh drivers...

another thing to consider.


With the release of a new card ...we all know its only a matter of time before Nvidia comes out with the perfect drivers for this beast....deffinitly allowing much better performance.

I think I will go ahead with the step up to an EVGA 7950GX2. Pay the 250 bux extra and be done with it.

I have convinced myself that the buffer and the extra 1 gig is worth it...not to mention that most games coming out will begin to use the 1 gig of RAM. Also the OC potential may be pretty good for me...I have GREAT airflow...not to mention I am running a 7900GT SS at 670/1900....impressive.

I also am considering the fact that Nvidia will win when it comes to the drivers. Its only a matter of time till nvidia will release the drivers that truly unlock the 7950GX2 from its cage.


FTW!

They need to release the Quad SLI drivers and let the real beats out the cage :D You made an excellent decision in stepping up, beats paying way more then you will if you wait and let the stepup expire. Plus you now have the option to go Quad once it's supported.
