UBIQ is a great coin based on ETH with a very good roadmap. Currently it's at epoch 6 and has 80 second block times, so it can even be mined with 2 GB cards for a long time to come (something like 6 years). Currently up 50%+, the biggest gainer today of minable coins.

I think it could take out ETC for the top ETH clone in marketcap. MUSIC and EXPANSE are other ETH clones that can be mined with 2GB cards.
