KEEP IN MIND THAT ETH MINING STILL PAYS BEST--
The new GPUs with more than 4GB VRAM will mine ETH. Miners with older, smaller cards need software that runs on older systems. The algorithms that you want to incorporate in your miner are just fine for the smaller cards.
Ethereum Classic (ETC) had a spike last week that had it paying second only to ETH. Not too long ago, before it forked, it paid better. I just need software that is going to run on my Linux rigs. VTC is my top earner for my smaller cards, but nVidia is left out. Software designed for the latest and greatest isn't running on smaller GPUs that fit the algos (VTC, ETC, ZIL) that need less VRAM.
