I recently got the Sapphire Dual-X R9 280X, And so far it is really great and can play most of my games at the highest graphics, but only for some time, After about 10 minutes of playing my PC gets really hot and my frames drop massively! too where they are unplayable, I'm pretty sure it need a new PSU. So could someone please recommend me a good PSU? Price doesn't really matter, I just want the best for my graphics card, Also here is a link to my case and other things http://www.amazon.com/Avatar-Gaming-FX6164-Desktop/dp/B00AZ428N8/ref=sr_1_1?ie=UTF8&qid=1407164216&sr=8-1&keywords=fx+6164+gaming+desktop
