By the by Sharky, I'm going to reverse my decision on ATI video cards. Had I the money, I'd scoop up an HD7990 or its cheaper siblings in a hot second. After doing some extensive reading on Lux and GPU rendering, ATI's newer cards are practically built for blistering GPU-rendering speed. These nvidia cards I have seem to be more like a hinderance because of how they coded CUDA. Damn!!
