Is it worth getting a BFG 6800 GT? I mean, can't I just modify my 6800 GT myself and get the same results, or do they actually modify the hardware to make it better? And how significant is it? Also, do I need special cooling on a 6800 GT (unclocked) in an unclocked athlon 64 3200 system? EDIT: I meant to make a new thread about this. The whole adding "Title" in reply kind of threw me off.
