What and how much do you lose putting a PCI Express 2.0 GPU in a PCI Express crack? I know the 2.0 can handle twice the info but for example: A GeForce 9600 GT has these numbers core650/shader1625/memory1800 and bandwidth 57.2. Do I cut those numbers in half in this situation? Thanks, HossHuge One other question if you have time. GeForce 9600 GT 512mb or GeForce 8800 GTS 320mb?
