My older PC's video card just kicked the bucket and has been BSODing. It has a PCI-E x16 slot. Newegg has video cards that are PCI-E x16, 2.0, 2.1, etc.
The slot on my ASUS P5N-E SLI motherboard is 16x. Can I use 16x 2.0 and 2.1 video cards in it? I'm not too familiar with how that works and couldn't find a solid resource on it through Google.
