I'm concerned I might have a bottleneck somewhere as performance is not quite what I'd expected when I brought my 2nd Asus 5850... I'm thinking its maybe not enough Ram or motherboard only running 8x when in crossfire?? System Spec: Asus p5q-e (8x crossfire) [email protected] 4gb Ocz reaper Ram 1066mhz 2x Asus 5850 oc @ 1000/4400 Coolermaster 850w psu 30" dell 3008wfp monitor When I added the 2nd 5850 I assumed I could run full settings on most games which im struggling to do at 2560x1600 resolution. When I used just 1 5850 I could easily run medium settings on games like bc2 etc. Was thinking maybe getting something like a Asus p5e Deluxe which is x48 but worried I might not achieve my 4ghz cpu overclock.
