Did u try your friends gpu in your system to eliminate that your motherboards at fault? Anyways somebody said get a used 775. F that. Never get used. I see new ones all the time on ebay and relatively cheap too. Look for x38 or p45. I got a new asrock p45 mobo for my q9550 system for $70. Anyways if it is your video card then a (AMD) 6850, 6870, new 7750, 7770 or new or used 6950 1/2gb should do the job. Nvidia would be gtx550 or gtx560. Always nice if u can stretch the budget a little more but its really not 4 your gain is it? Yes i would wait for the new nvidia cards which should shake the market a bit. Good luck. P.S. My 780i went ages ago!
