pci-e 1 video cards/slots are x16 vs 8x agp
the revision 2 supports higher bitrate but all this is backwardsly compatible, the older pci-e cards work in newer slots and vice versa
the performance difference of using revision 1 mobo with revision 2 card would be minimal
you are safe with that card as long as your computer has enough power and cooling
