I have a Pentium 4 530 3ghz and i am wondering will an 8800gs make any impact over my 7600gt? Right now i get like low 60's to 100 fps on 1024x768 low settings. What i am looking to do is play COD4 on high settings at 1024x768 reso with no less than 50 fps, can the P4 not bottleneck and let the card do its job?
