Yeah, that board doesn't have a normal(PCIEx16) slot for video cards. You will be stuck with PCI cards and they are both weak and overpriced. The best you can do is a 9500GT and I believe it will be limited by the interface;http://www.newegg.com/Product/Product.aspx?Item=N82E16814187083
That motherboard on its own is $156 anyway. For the less money you could get this;http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.478082
and 2 gigs of DDR3;http://www.newegg.com/Product/Product.aspx?Item=N82E16820148352
The motherboard can also unlock the 4th core on the processor.
