It would be best to check with your manufacturer.

Don't make any decisions based on my post alone, but I think I've read somewhere that all PCI Express versions are backwards-compatible.

i heard from my friend on school who knows a lot about it and he said i could use PCI 3 cards on PCI 2 slots, but the speed will be slower, and the same with PCI 2 cards on PCI 1 slots.

Solved.
