I have dual 8800 GTX in SLI in my Dell 720 XPS and I am looking to see if I replace these "older" cards with dual BFG GeForce 9800 GT Video Card - 512MB GDDR3, PCI Express 2.0, (2) Dual Link DVI, HDTV, VGA Support. Reason is the card drive keeps give a none responding error and I think it is due to over heating of just being older. I don't do any heavy gaming except for C&C Red Alert 3 and Left4Dead and Photoshop. I can get two of these for 200 bucks and hopefully put these errors behind me. Any thoughts? Thanks
