First off I am new to the whole Quad crossfire x setup I am using 2 Sapphire ATI Radeon 2GB HD4850x2s single bridged {x16,x16,x16,x16} I get half the amount of FPS with 4 gpus than i get with 2 gpus and also while playing crysis my cpu gets so hot that it restarts. I am currently using a stock cooler but buying a new cooler this week. Is this normal for quadfire to over heat my cpu? We're talking 80 celcius my other games don't do that not even crysis warhead just crysis any advice?
