I have an XPS 8300 with an I5 2400 3.1 Ghz processor 8 gig of ram a stock PSU rated at 460 Watts. I've read that there are Bios issues with some cards and the cards recomended by dell on the forum are hard to find I did find a hd 6670 from gigabyte my card that failed is hd 5670 from Dell. Dells forums have me more confused then ever. Thanks in advance
