Definitely get a PCI-Express 2.0 card Lots of them out there, but 3.0 is the new kid on the block depending on your budget, a GeForce GTX 650 is pretty nice... PCI-Express 2.0 cards: $124 GTX 550 Ti$250 GTX 560 Ti PCI-Express 3.0 cards: $109 GTX 650 $150 GTX 650 Ti There is no guarantee these will work on your board because they are 3.0 What kind of MSI board do you have again?
