320Mb will be fine till u reach 1600x1200 or sometimes till 1920x1200
early DX10 benches show the 320mb struggling much sooner than the 640mb, for the small price difference I'd recommend the 640
Hey if you'd like to buy my 320, I'll buy a 640 for myself. I can't stand the way my 320 sputters and spits in outdoor Oblivion, and that's only at 1280*1024 with all details up and HDR, also with draw distances maxed out.
I think the 320 has real problems with texture swapping, and it is my opinion that the benchmark numbers we see online do not reflect the pauses that the card experiences during swapping.
On the other hand, when the card has all the textures loaded, it processes them incredibly fast, so if you can live with some of the settings turned down, or a little less resolution, you will have a real fast card on your hands.
No i disagree the 320meg version has no problem with that resolution ,
i play at that resolution.
It depends on the games too. His favorite games may be more demanding than yours. Also, are you playing with all the eye candy enabled?
I take strict offense to this
i play all the candy available dude , i mean i got the whole chocolate factory killing it
