I am going to get a second Twin frozr 7950 this eve and I was wondering can they both be overclocked. My current 7950 is at 1.2 1150/1475. I'm guessing i will need to test the new card alone and see where it can be clocked to and find a level ground to set both to when crossfired if thats even safe. Also my case is only a thermaltake commander with a front intake 120mm and top and rear exhaust 120mm, I'm going to get a corsair graphite 600t but not for a few weeks. Will crossfire, overclocked or not, generate too much heat for current case and cooling? Is it safe to use my current case or should i wait to start crossfire when I get my new case? My temps never get above about 62C when gaming even in bf4.
Thank you in advance and any info you need from to determine a better answer feel free to ask
