If you're up for something new, I'd like to suggest MYR, which has an interesting combination of different algorithms, each with it's own difficulty but all at the same rewards level. Particularly one algo (groestl), is only mined with CPU/wallet at the moment, so possibly an opportunity for cudaminer to standout

I'll be happy to test support for this on a GTX770 and/or GTX750TI (oh, but I'm unable to compile myself)
Cheers,
