i got the geforce 8600 gt the other day from newegg and my pc won;t boot up when it installed, but its okay if i have my old 7600 gs install. i was thinking of getting a more powerfull power supply this tuesday to see if its the problem, though its 500 watts with dual +12rails with 18 amps on each of them. i was thinking of getting the bfg model here:

although this seems good as well:

what would you suggest?
