i built my system new system about a year ago, and transfered over my 512 mb 8800gt ssc, and its been a champ for almost 3 years running now. i want to go another year on my 775 platform by just upgrading my gpu now. right now i have a q9550@3.8 air, 4 gb g skill ddr800,p5q pro asus, and a hx520 corsair psu..... would a 5850 be decent (when they are avail)? this way i wouldnt have to upgrade my psu, or could i get away with a 5870 on my psu? and keep it for another 1 year with my platform...any other suggestions without changing my board would be useful. im really just trying to keep my psu, board, and cpu for as long as i can, but get a very nice gpu to throw on it now or in decemberish. thanks. i play crysis, tf2, lfd2, crysis 2, and other intense fps.
