I've been having some frame rate problems with my Sapphire Radeon 5970. When playing Dead island 2 I get 40 fps and Deus ex I get round 65. I just installed my other gpu (MSI Geforce 275) and I'm getting like 100 fps in Dead Island and 90-100 in Deus ex.
Has any1 out there experienced the same problems? Certainly my PSU is sufficient to run the Radeon 5970? I also always use the latest GPU drivers. Do you guys think the Radeon is faulty? Please help!!!
