Either way Raging, and don't hate me, the 6990 would be the better choice, not only because it's the more economical choice for GPU horsepower on his end, but also because it's the better card. eek.gif

(waits for the flame war and a stinging rebuke)

You don't understand how nVidia's memory allocation works, its not loading always just whats needed, but caching textures. I have already talked to Skyline, his numbers are artificially high, because thats how nVidia has optimized drivers for the larger VRAM modeled cards.

Here is Heaven maxed out at 4xAA:

Here is a screenshot from DiRT 3 from my benchmark thread:
Ultra Settings + DX11 + 5760x1080 Resolution and 8xAA

The VRAM misinformation is really bad from both camps. People trying to justifty their purchases I guess.

Regarding modded games, you can bruteforcefully maximize your VRAM usage in just about anything. I am talking about games you buy off the shelf and play. Dragon Age II is not suitable for 5760x1080 with more than 2xAA, which is why I said its not suited, even though it requires the official DX11 patch and high res textures to get that "demanding."

OP:
Having a 6970 already, I would look at a 6990 option. Just makes more sense to me.

Does the same apply with the 3GB 580? If I got just the 580 I'd still have to turn settings down for 3 monitors, yeah?

Well yeah a 6990+6970 is a tri-fire config. It seems the optimal route for you since you already have a 6970. Tri-fire setups aren't perfect but they usually scale very well. Regarding the 3GB 580's no, you would still want two for an SLI. But that's the Crème de la Crème so to speak.

Ah I see. So the GPU's with more VRAM are you the extra availability like a prefetch cache to increase rendering? Or was that way off the mark? Either way, my mistake and thanks.

No biggy just like clearing things up. The huge benefit of the extra VRAM at low resolutions is honestly loading times to a certain extend and reduction in texture pop-in... the loading technique of textures suddenly popping into the environement as you get closer to them, to lower GPU memory footprint. nVidia almost eliminates this by driver + game willing on the 3GB models.

Well thanks everybody, it looks like I will look into a 6990, if they ever come back in stock at Newegg. Or I'll have to scour for a used one.

I may just wait for BD to come out so I can do everything at once. Just swapping out my mobo a couple months ago was enough of a pain to make me not want to upgrade so soon haha.

Good luck with your next purchase!
Buy sapphire hd6990+ FX 8150 when it comes out.
