I been having heat issue with it but that might be more cause my old 8800 are slowly dieing. I know they added some number which is supose to control im guessing the cpu workload allowing it to feed the card more. At least that is my understanding of it, i know there is a thread about it on the forum just dont know which thread it was maybe someone can link that for ya. Im having such an issue with my internet atm that i constanly have to refresh pages to get it to show up or i would try to find it... This new uverse stuff has been nothing but a nightmare and now that i signed a 1 year contract im screwed for a year ugh...
