OK, I have some questions about the compatability of PCI Express cards. First; is a PCI-E x16 card compatable with a PCI-E x16 2.0 mobo? Also on the same note, is a PCI-E x16 2.0 card compatable with a PCI-E x16 mobo? Second; how much performance does the PCI-E x16 2.0 have over the PCI-E x16?

Yes, Yes and 2.0 offers twice the bandwidth but since most cards don't use more bandwidth than what's available in the original spec it doesn't make a significant difference.
