Quad Sli OR 2x9750 GX2

Hey im selling 2x EVGA Geforce 7950GX2… they are PCI-E cards… bought for 750+ taxes each… only reason im selling them is because i want the new 8800 series cards. in total, each card has 1GB of video memory, and can run 16x AF and 8xAA. when in quad sli, they can run 16xAF and 32xAA. Best possible video quality out there for anything. gaming, creation, editing, anything. Asking 700 for both… or 375 each. thanks!
