Ok, this may be a stupid question to ask. I was going to go sli on a new build and i was going to buy 2 pcix 2.0 cards, my question is are the express 2.0 cards backwards compat with 16x slots? Its a nub question but i never took the time learning my self.. about pci slots I always went 2.0
Don't go SLI, that requires an SLI motherboard, and these are universally poor. If you need a fast card, get an HD4870 or GTX260, or if you want very high performance, a Radeon HD4870X2. This means you only need one PCI express slot, and can get a decent motherboard like a P45 chipset.
Yea i have a geforce chipset right not, I would probably go with the gtx but my board only has a pci x16 slot will the pci 2.0 x16s fit in them?
