I bought an 8800 not long ago. Its the 768mb one, the big mutha *$&%. Anyway... I'm running it and all my other techno-crap off of a Mushkin 550W psu. It runs alright, but I seem to be having hampered video performance. After reading many reviews, I'v noticed that this card seems to be the messiah of video, but I am unable to run games such as second life, joint ops and even programs like 3Ds Max at the speed I would like to. It could just be me, but I receive a lot of crashing and video related glitches in those programs (flicker, major lag, etc) anyway, I don't get the great fps I want. Any ideas on what might cause this ?
