The 4GB 670's aren't even better in 2xSLI, at Surround Resolutions (vs 2GB models) ...

post #1 of 20
Thread Starter 
I know this has been posted in the news forum already, but I figure we can also talk about it here in the nV forum since the topic of the 4GB cards has been debated endlessly.

I lobbied a bunch of times on their forums for this test, SO happy they finally did it, so we could put this debate to (something like a) rest.

[H] has determined that the 4GB cards don't offer any tangible gameplay advantages in terms of 'max playable settings' (at least, not in their suite of games) over the 2GB cards even when run in SLI, at 5760x1200 resolution.

The GPU power ends up crapping out before the 2GB buffer does, even with two of them, at surround resolution.

If you read the details of their conclusion, however, they did admit that in Hitman, the 4GB card does allow using 4xMSAA, provided you don't mind the occasional slowdown (w/only 36 avg), whereas apparently the 2GB card really tanks (abysmal 25fps avg). But they had to drop resolution to 3 x (1680 x 1050) monitors, otherwise both cards lacked the GPU power to run 4xMSAA!

Interesting, indeed.

This comes really close to settling the matter for good AFAIC ... aside from perhaps texture-modded situations, the 4GB card is really no better than the 2GB card. Unless MAYBE ... if you have 3 of them.

Maybe we'll get to see that test someday from [H] thumb.gif

This is actually a relief, so now I don't feel bad about getting the 2GB version versus the 4GB. specool.gifwheee.gif

GTX 670 4 GB is good for people who run alot of texture mods especially in games like GTA IV & Skyrim (reduce stutter).
But at high resolutions it will run out of GPU power before running out of VRAM.

This. Also, if anything, 4GB is a little slower. Timings have to be loosened with the larger amount of RAM.

The hitman example just tells me it's a good idea to get the double vram. Think about how much money you're spending in the first place, why skimp? I'd feel pretty crappy spending all that money and just seeing it crap out like that.

Tri-SLI in surround is abysmal. Dual-SLI is the best scaling for triple monitors. Third and fourth cards aren't worth it. 50% and less GPU usage. Tri-SLI for one monitor? Good to go.

I suppose that's one way to look at it. But when you really consider the two options presented:

Option 1 (2x2GB)
- Save $100-120
- Play the game at full native resolution (3x1920x1200)
- Use FXAA Only
- Average 63fps/Min 28fps

Option 2 (2x4GB)
- Spend extra $100-120
- Play the game at (perhaps a) non-native resolution (3x1650x1050)
- Use 4xMSAA
- Average 35fps/Min 0 fps with lots of time <30fps

I think I end up feeling okay going with Option 1, and the $100 in my pocket. Even looking at the comparison at 2xAA and full-native resolution shows way too slow of performance on the 4GB cards for me to call it 'playable' ... I'd never use those settings either ...

This review pretty much shows you're better off spending the extra dough on a couple 2GB 680's vs. the 4GB 670's.

Also, Derfer ... profanity is not allowed on OCN, even when it's covered by **** thumb.gif
