I'm a professional Litecoin miner. BTC is careening towards ASICs, especially given the ~25% difficulty retarget this time around.
For those that don't know, there are application-specific integrated circuits that are about 30x more efficient per dollar and watt than a GPU. That is why you can't mine many BTC with a good card. This is also why people are going over to Litecoin for GPU mining.
Back from the dead, I'm afraid.
