Casecutter, I received and installed the ASUS 4670 video card per your instructions without any problems. The BIOS looked different from what I was used to, but I figured it out. For what it's worth the new video card increased the graphics experience rating from 4.5 to 5.9 and the game graphics experience from 3.5 to 9 I am very happy with my new computer. I also purchased Norton Internet Security from Ebay for $11.50, 2yrs for 3 computers. Thanks again, Wolfpackron.
