Kind of disappointing, almost no benefit to having the 2gb compared to the 1gb of the vanilla 5870:

Wow, that sucks, i thought when enabling AA in some games the performance would be totally different, oh well

When enabling AA in cases then it will be different, i.e.:

It's very game specific, but im sure if a game can take advantage of it you'll want the extra vram.

Any scenario which takes the required VRAM over 1GB will show advantages for a 2GB card. Remember Doom 3 and it's 'Ultra' quality setting that needed a 6800 Ultra with 512MB of VRAM to do it half decently?

But the extreme VRAM requirements mean that it'll need very high resolutions combined with Anti-Aliasing. Or buckets of texture mods for a game.

I'm sure, given that I can get Oblivion merrily chowing down on 912MB of VRAM at 1920x1200 0xAA with some texture mods that EyeFinity with texture mods would probably make a 2GB card cry.

Of course, having said that, I've got no way of testing that right now.

To be honest, I'll want to see for myself rather than go by reviews... I've seen far too many reviews out there that don't even bother looking at scenarios where a card might fly, because it's outside of their standard benchmark suite. That said, Anandtech is usually pretty good at that sort of thing.
