Summary: Runs on 4.5GHz no problem. Haven't tried to go above - more than enough already. Stays really cool even on full load for hours. MUCH cooler than my previous 3.7GHz 4core AMD. Awesome CPU for the money.
Summary: This processor was purchased for a dedicated audio workstation and also for the occasional pc games and other intensive programs and creative software. It has solidly ran since the day I received it, and do not expect any change in the future. Word to the wise, however, this processor gets HOT. Be sure to have adequate to excellent ventilation, and water cooling. It is designed to be used best in conjunction with a water cooler.
Summary: This processor works great, and the performance is definitely noticeable. The windows experience index assessed this processor at 7.4. Definite performance increase from the quad core I had previously!
Summary: This sucker is fast! Windows 7 rates my PC at 7.9. I have this running with an MSI Radeon 7870 Hawk. I run all my games on Ultra without any problems. My PC never gets too hot even after long sesions. This is a greta buy!!!
