Asus or Sapphire HD4850 512 Mb

Which HD4850 512 mb should I get? I heard that the Sapphire has better cooling.
People!! Please tell me which one I should get!! And also, how much FPS gain would I get for games like TF2, COD4, Crysis, Fear2 and COD5 if I got two HD4850’s and Crossfire them??
And most importantly, is my PSU enough for crossfire and everything I have?
And also, does my motherboard support one HD 4850? Does it support 2 HD4850’s Crossfired??
Thanks a lot!!!
Btw, is my Antec Nine Hundred good enough to OC my CPU to 3.0 ghz without after-market HSF??

  1. First the Antec case is great for air cooling.
    The PSU, is it up to the task of powering your desired card, chec with one of the PSU calculators.
    I don't buy Asus anymore because of the **** tech support.
    For ATI cards I only buy Visiontek retail cards for the lifetime warranty.
  2. DO NOT GET THAT PSU. Get a Corsair 550VX or even better a PC Power & Cooling 610.
