CPUID HW i see that one of the temps is 79'c do you know what it is as i haven't used that program before, your core temp readings are not at all bad for a 3.2Ghz x2 i had my old x2 6000+ running at the same speed and was around the same temp so i would say it's possably not that but they are not 100% load temps, could you post a pic of a 100% load reading
the ocz psu above should do you just fine, can't remember if i said above but i've got a 600W ocz gameXsteam firstly running my 6000+ x2 and 8800gt sli and at the mo running my current set-up and it's about 18 months / 2 years old now and still going strong
also silly question but you do have a surge protector on your pc don't you, i ask because a mate of mine who's been into pc's for years and has only just got round to buying one
