I recently come upon a nice server with pci-x slot , but no pci-e slot . although easy to confuse the two by name , they be not interchangeable . this pcus revision 2.1 fit perfectly into a pci-x slot to upgrade my Intel server to Windows 7 compatiblity with Aero-View . the onboard video be not design for home entertainment and barely have a 1.0 Windows experience index , but with this board the index come up to 2.5 , and Windows turn on Aero-View after the rating be update .  evga geforce 6200 512 mb ddr2 pcus 2.1 VGA\/DVI-I\/S-Video Graphics Card , 512-p1-n402-lr
