You can't get any of those cards if you have a junk 400W. (most good PSUs would be 380 or 450W.) Get the cheaper of the GTX460 or 6850. Spend all your other money on a new PSU. Should be able to get a good Antec, Corsair, or Seasonic for $50ish.
well the GTX 460 draws a max of 160W as compared to a new 560 draws 150 watts maximum and that requires a 450 watt power supply. actually i just checked and they both need a minimum 450 watt power supply which aren't expensive at all. you can get an Ultra 550 watt at tigerdirect for $50 (http://www.tigerdirect.com/applications/SearchTools/ite...) with a lifetime warranty. i run one of their 600 watts and i've had 4890s and 9800 gts in my case, as well as multiple hard drives eight gigs of ram, two nics and a phenom x3 processor in an Antec 900 case with three 120 mm fans and a 200mm and it never crashed or showed any signs of overloading. Considering that you can get a GTX 460 for +- $135 and the psu for 50 for under 200 you can get a great psu and a great card. At TigerDirect both come out to $223.xx with econoship which is only 7 dollars, and theres a $30 mail in rebate for the 460 so you walk away in the end with both for just over $190, under your max price cap of $200. Good luck!
thx for help ; me 2 i like ATI cards more than Nvidia
I'll just wait for price drop if not i think i'll go for the HD 5770 seem to work fine with my PSU and monitor res , look like i can maxed out the newest game with that card ( crysis 2 , metro 2033 , Black ops ... )
Any other advices =) ?
I know the budget is $200, and that's already pushing it, but if you can get that antec and the video card I linked you'll be in much better gaming shape. Perhaps buy the PSU this month and the GPU next month? If not you do have to live within your means so perhaps someone else knows of some better deals.
