Tsssssssss, liar, liar, pants on fire !
I know just exactly how you feel ; why in heavens name did i buy this card ? I had mainly booting problems with it, it wouldn't sometimes boot for 2 or 3 times giving black screens and all. Also a lot of in game crashes. Happily i paid just round 150 euro's for it ( 180 dollar ? ) Should have been a clue actually, prices dropped from 300 to 140 . . . But still, when it worked it was great, colores were fine with mine.
Anyway, just to be sure ; you did download the latest drivers i assume ? And maybe try to get the colors better with the NVidea settings, something like "digital vibrance" does a lot.
Would still like to know your mobo, psu, ram, budget and so on.
