SHA-3 is great imho - my cards run a t a lower temperature, and my rig uses about 20% less electricity mining MAX - but with the lowering of value, it's no longer profitable for me to mine, so I have switched back to Middlecoin, mining Scryptcoins.
I will hold my MAX though - no choice really, having spent 1.5BTC on a pile near the top - thinking it was moon-bound, and having mined another 2.4BTC worth (at that earlier top), it's not worth me cutting loose, I'd only get 0.5btc in total right now, so I guess I'll go long term.
A friend and I are working on a lottery website now though in our spare time (currently DOGE, but will be expanded to many coins - and the next will be MAX) - one that uses the blockchain properly for picking the winner - so hopefully in a couple of weeks when we have all the bugs ironed out, that will be something to look forward to!
