Ok, I have a Gateway Media Center PC with an X2 4200, 2 gigs of ram and a 300 gig hd. Its got integrated video right now. I am looking to add a vid card to pair with a Dell 19" monitor I have. SO I have narrowed my choices and so far I am looking atX1800XL, or X850, or X1800XT or the bidget card 7600 GT. They also have X850's for under $200. Also, my PC has a 300 watt psu, would that be enough to push any of these and if not, are propriatary PSU's upgradeable?? Thx for all the help.
