thanks in advance i hope i have provided the right information you clever people need,
thanks mark.

ive had good experience with XFX customer support, had a video card burnout after couple months of using (7900GS AGP). (overheated to 75C then stopped working), RMA'd it they tested it and found it faulty, but they offered me a 8800GTS 320 pci-e replacement because they were out of stock on the 7900GS AGP. i find that a big plus for customer service and will definitely buy from them in the future.
