my sons (older system from the summer) w/ vista 64bit hp
E8500 is running 3.8ghz at 425 fsb on a asus p35 p5k pro mobo
running Gskill pi ram at 850mhz 4-4-5-14 at 2.1v sandar is an amazing 7,825mhz
with a 3870X2 18k+ 3dmark06
temps with prime95 45-46c at 100% !!!! how that for low! (ok the thermalright ultima90 properly installed with lots of thermal past and dual fans is overkill)
good luck!
this computer is very very fast and repsonsive - if you do not multitask - great systems. otherwise a q6600 for multitasking or i7 is better
there is your settings
