Gents,
Does anyone know wether 2 8800GTS 320 are faster than one 8800GTX.
The cost is about the same.
Cheers

I vote 8800gtx, but here are some benchmarks with 2x 8800gts 320MB SLI Link

If you want to run your games at over 1600x1200 then i would go with the 8800gtx but if u wanted to keep it at 1600x1200 or lower i would recommend the gts's in sli.

That Guru3D link has the GTS SLi vs GTX SLi not against a single GTX.

I realize that, but it's the only guys who did 8800gts 320Mb in SLI as far as I know. You can always compare the SLI benchmarks vs the single card benchmarks in the previous pages. And just for your convenience, here they are:

Thanks for the graphs.
seems SLI with 2 cheaper cards is USUALLY better. Depending on the title.

A shame that they dont test any flight sims.

Cheers

8800GTX; less power used, upgrade path, 768MB vs. 320MB. (SLI does NOT add memory)
I always thought the SLI adds up the memory of the 2 cards used. I thought the way it works is SLI splits the screen and half is rendered by one card the other half is by the other. I am n00b to SLI but for some reason that is what i thought. :)

I am in the decision making stage as well wether get an overclocked GTX like EVGA's AC3 or superclocked GTX or should i go for 2 x cheaper cards in SLI.

He's right, SLI doesn't add the memory. So saying that you have 1GB of GDDR with the 7950gx2 is a half truth, or any other SLI or crossfire setup. Let me put it to you this way, video memory gets taken up mostly by geometry data (think wire frame) and textures, as far as I know. Obviously your PC can't predict what to render until it's absolutely needed. For that reason both video cards hold the same data. Video cards can't send this kind of data between themselves either. There is a reason new video cards are pushing nearly 100gb/s through the memory, and that kind of bandwidth just isn't available for transferring that kind of data between cards. Someone, please, correct me if I'm wrong.

In that case it is a no brainer that one GTX would kick the sh1te out of the SLI GTS cards even if you SLI 2x 640Mb GTS cards, because what i have heard is that in the DX10 games you will really need all that RAM that's on the card because those pretty textures will take up a lot of space in from your RAM.

I suspect the R600 cards will pull ahead in that department since i think they are going to use DDR4 ram and also their high end cards will have 1Gig of ram instead of 768Mb like the GTX.
