As a GPU miner which i am not. i would seriously evaluate ROI point and resale value to get ride of GPU mining and investing same capital to BTC or something else. Waiting for next wave of hardware mining. Early adopters always gain the benefits. The people who are planning to make 8, 12, 16 GPU rigs now... dont, you are too late. Goldrush is gone.
Bad advice. GPU mining will allways be more fun and risk free than entering ASIC spiral that streams all the coins to ASIC sources. If scrypt coins developers want, they can make changes towards different algo. GPUs will adapt, what will happen to scryptASICS? They will continue diving into BTC ASIC spiral. That's why nobody is producing scrypt-only ASIC.
