2 6970 or 2 Gtx 580? - Page 2

post #11 of 60
580 1.5Gb are overpriced POS. Buy 2X 6950 and unlock them. The 580 are not worth the extra money.

And with the money you will save, buy a better monitor, or 2 other to go Eyefinity.

And they are definitely comparable, especially in Crysis, where ATI does surprisingly better than Nvidia.



Those are 6950s Crossfired, getting great results (almost twice faster than a GTX 580), so 6970s would do even better, at least in Crysis anyways.
Doh, that was noobish for me to figure the vram was doubled and I should have known that playing GTA 4 with two GTX 470's.

But I am surprised by them results. Always thought that GTX 580 single or SLI beats 6970. Still, not 100% convinced with that one test.

Not gonna argue too much since I have a 6970,lol.

You definitely got a good card, especially for Crysis.

Lol who plays on that resolution?

That's the only case where VRAM is more important than the card itself.

I would say value for money, 2x 6970 or 2 x 6950 unlocked for sure. I don't think the extra price for GTX 580's is worth it. But like I said, if money isn't an issue, GTX 580, or look at the 6990'S even.

So long as he makes sure the 580s have more VRAM than the 6970s, and if money is no object for his upgrade, 3GB 580s, otherwise best to go with 6970s.

So basically you are spending ~$1000 on GPU's if you are considering two GTX 580's.

For that price you can get one HD 6990 + one HD 6970 (or 6950), and they will vastly out perform the two GTX 580's.

In fact, Crossfire scales so much better that the same 6990 +6970 even beats Three GTX 580's, at $500 less:
