Given all the ASICs coming on board over the last few months, building a GPU miner for BTC seems like a hard sell given the difficulty and hashrate of the network. But is there still opportunity in GPU mining LTC since there isn't an ASIC-effect yet? Are there any good calculators to determine profit for LTC?
