Hi, Just a quick question (or so I hope). Will the nVidia 8800GTS 512mb Graphics card work with my Motherboard; the nVidia 650i SLI? I have read around and dont really understand anything. Some listings say the 8800GTS is PCI-E 2.0 while my motherboard is only PCI-E and vise versa. Any help will be greatly appreciated. (Also how do I find out my PSU voltage rails etc? I was told the 8800GTS need 8 12v rails (or something along them lines), I have a 500w power supply if that helps, cant say what make, sorry).
