Any PCI Express card should work however take note of the following as I could not find the exact specifications of the PCI Express slot on your motherboard except that it runs at 16x speed.
1) If you buy a card that is PCI Express v2 or v3 and your motherboard is v1 it may not run at full speed (but should still function just fine)
2) Make sure your power supply has the correct power connectors available for the card you wish to buy. Some take 6 pin PCI-E power connectors, some take 8 pin, and some a combination of the two. (open your case and find out)
