Ok so I put up a rig not too long ago. Bought one 8800gts 512mb pci-e x16 I was planning to buy another later on to go sli. Now I go to newegg and evga that vid card has been discontinued already... so I see this new 8800 cards but they're pci-e 2.0 x16, would they work on a regular pci-e slot? or not?
