OK so forget about heat and all of that stuff... I want to know if I could throw in my old gtx 260 in with my 7770 cf setup. I know about the old hacked drivers and stuff but without those would it help at all? My other question is could I buy a 7750 andput it in with my 7770cf setup, I think this might work because the 7750 does not require a external cf bridge?
