d6bmg Posted September 9, 2012 Posted September 9, 2012 (edited) I think 850 is plenty for 2 card setups. You may not need a new PSU. Unless he is planning for 2x GTX590/690 or HD6990/7970. Edited September 9, 2012 by d6bmg Share this post Link to post Share on other sites More sharing options...
Waco Posted September 9, 2012 Posted September 9, 2012 Dual 7970 would be fine. The others are quad-SLI and Quadfire and would definitely need a new PSU. Share this post Link to post Share on other sites More sharing options...

IVIYTH0S Posted September 10, 2012 Posted September 10, 2012 As cards get become more efficient my 750 definitely should be all I need, CF/SLI included Share this post Link to post Share on other sites More sharing options...
Waco Posted September 10, 2012 Posted September 10, 2012 As cards get become more efficient my 750 definitely should be all I need, CF/SLI included Definitely. There's no single card (or two single GPU cards) on the market today that need more than 750 watts at full tilt. Share this post Link to post Share on other sites More sharing options...
