Will work fine with your motherboard, as long as the slot you're putting it in is an x16 slot (the long ones)

Shouldn't have too much of a performance drop with it either.

Got to the link above. Go down the list to Expansion Slots. Red I colored and is for the video card.

Expansion Slots.
1 x PCIe x16
1 x PCIe x1
2 x PCI

The PCIe x16 if it is 2.0 does not matter. The 2.1 card is backward compatible to a 2.0 slot.
