I have the opportunity to pick up a second EVGA 8800 GTS 640 SSC card for $140 bucks. I will be using it half the time on a 22" monitor, and half the time on a 37" plasma. I also want to be able to prove to my father-in-law that these two cards in SLI will make his PS3 bow down in respect in COD4. Yes, my father in law is 66 and plays COD4. Whaddya think? FYI, only have a PCP&C 610 watt in this system, don't want to spend anymore on another power supply so I'm going to get an epower 450 5.25 drive bay power supply on top of my PCP&C 610.
