Hey, I just built my new rig with asus rampage ii extreme mobo and i7 920 cpu. i did a fresh install of windows vista 64bit, and it is running really really slow. Even my old e6600 ran it way faster than the performance i am getting right now. i have everything in the bios to default settings. Do I need to change something in the motherboard settings for hard disk to make it perform better? or does anyone know what might be the problem??
