I decided to run the ice storm demo from futuremark which is made to stress all four cores in a quad system... Well two things I noticed 1. My max temp was 68 c and 2. Asus probe and CPU-Z reported my vore core dropped from 1.3680 down to 1.3000 or lower... IS that due to power draw by the CPU's and possibly not having a large enough powersupply??? I have a 8800 GTX and a Q6600 with 2 GB of ram two hard drives.... So I guess I am asking is this normal or does my 620 Watt enermax psu needs to be replaced... I hope not the guy at the PC store said that 620 watt will be more than enough power for my current set up....

If you are air cooled 68c is not too hot at load. I wouldn't want to get any hotter than that. Keep in mind that the temps you get in a stress tester lilke orthos are far higher than you will encounter in day to day use even in heavy gaming.
