well its certainly not going to be a huge upgrade, not really worth it imo, if I were to upgrade from a gtx 275 I'd at least shoot for a gtx 560ti, 5870, or 6950 level of performance, maybe more
see the thing is I can get the card for less than nothing so ya, jst glad ist better tha the 275, saw its better than the 6850 and the 285 aswell! so im pretty chuffed.
