Its funny how when this thread was created, all we were seeing were photos of GPU rigs, then photos of ASICs, and now we are back to photos of GPU rigs.
Haha! You are forgetting that short but sweet FPGA time.
I'm still burning those zTex x1.15 on Vcash, more than I can say about those 65nm ASIC!
FPGA's were available almost as long as GPU's were able to mine; their time wasn't short. Many miners simply didn't want to have a longer roi for better power efficiency.
