None unless your hitting a VRAM Wall. Means 2 of those in surround are more likely to run out of horsepower than hit single digit frames due to lack of VRAM.

If you are using a program or playing a game that needs more than 1GiB of VRAM, you will a large boost in performance with the 2GiB version. If not, you won't see any difference at all.

At this point I'd get the 2GiB version, if it's a good deal, especially if you ever intend to SLI the card.

I have games that will use 1.6GiB of VRAM at 1920x1200 with 4x AA.

What mostly uses the ram? I'm get it instantly but it's a Zotac, and reading reviews it seems they run like 15c hotter than asus and even hotter than reference. But those are the 786mbs.

most games dont use a full gig but more and more games are starting to use over a gig
for those games you will get more frames per second with the 2gb
i did see a review of 2gb cards that showed the difference but cant remember where

Ok, it's like this. Extra VRAM (1GB vs 2GB) provides no performance increase over the other. The only time your 2GB 460 would outperform a 1GB 460 model is when you have reached a VRAM wall. This is typically only encountered when playing at a very high resolution, or using lots of visual mods (Crysis Texture Mod, Oblivion Texture Mod, etc).

At a higher resolution, using more AA for example will eat up more VRAM then using that same AA setting at a lower resolution. For instance, most games I play at 5760X1080 (3 monitors) instead of 1920X1080. Maxxing out settings (Depth of Field, Tessellation, AA) requires more than 1GB of VRAM at 5760X1080 in a some titles. There's a thread around here showing VRAM usage at different resolutions if you want to search for it.

The above is a bare-bones answer explaining the results to you without the why. If you really want to know they why, feel free to ask and I'll be happy to go more in depth. Most people don't care however.

As for the cooling (noise, temps, etc) of that Zotac model, I have no experience so would be unable to tell you.

Okay thanks for the information.

Also so AA usually ram for the most part?
