I'm running an i7 920 with 6 gigs of ram and a radeon hd 48xx under windows xp64. I don't remember the exact model but its has 1g of graphics memory and i play at 1152x864. Graphics performance is fine, and while I'm disappointed with how much resources civ 5 inexplicably uses, game performance is ok too. Turns are sometimes slow, especially late game on large maps, but not unbearably.
I do get strange annoying issues where the game inexplicably has to page in data, typically either terrain textures or unit graphics. The terrain looks ugly but doesn't really affect performance. When it has to page in a unit, the entire game locks until it finishes paging.
Ive noticed civ V constantly uses just under 2 gigs of memory late game or on larger maps, and that and a comment someone made about it being a 32 bit executable got me thinking. I think the reason i see paging with plenty of ram free is because civ is hitting the memory address limit for an individual 32 bit priocess.
From what I'm seeing, it looks like civ 5 wasn't complied with large image support, and so can only use 2 gigs of memory max and begins paging when it hits this limit. I suspect to fix it would require a recompile of the exe, not just the dll, so I'm probably out of luck even when the sdk is released.
edit
actually i think this applies to any os version, i think i misread microsoft's table. Can anyone confirm civ V actually using more than 2gB of memory? I was looking at http://msdn.microsoft.com/en-us/library/aa366778%28VS.85%29.aspx
