I own a 8800GTS 640 OC to clock 658, Shader clock 1600 and memory clock 1050. I have a chance to get a 9800GTX 512 for 85$ from my friend who is upgrading to a 260. My question is i game on a 1440x900 monitor and the only thing i cant max out is crysis. Would this 9800gtx be a good buy? Would i be able to see any differences or am i wasting my money?The 9800GTX specs are 675 clock,2200 memory clock and the BIG one, 128 streamers VS my 96 on my 8800gts640.And i plan on OC the 9800GTX as well. Would this future proof me a little better then the 8800gts640 on the 1440x900?
