The 320MB doesn't perform well in resolution of 1600x1200 or higher, but it performs equally to the 640MB version at resolutions lower than 1600x1200
Yuo missed the question, he is already decided upon a GTS, it is now a question of a 320Mb GTS or a 640Mb GTS.Yes, but that's using dx9 games.. i believe dx10 will be much tougher on the resources than their predecessors, Especially the later dx10 games. So if yous gots the monies... get a GTX. If not a gts aint that bad.
K. well, the 640 is only $75 more...I'm not sure still...
