yes at stock speeds it would run between 95-100%, O/C it stayed closer to 100% the majority of the time I got this combo in the hopes of saving space/money over a normal CPU/Video card, as it sits now i'm more or less happy with it, but if I were to do it again I would just get a standard CPU and video card i've been running into nothing but problems with this APU everything from the system just crashing, to failing to install windows I had re-install windows something like 5 times last night.
