While gpu miners can now mine MMC, it's still not much more effective than cpu mining. It's the same with PTS, there are gpu miners, but you can still take part with a cpu with an almost equal result
There's even one advantage: botnets won't be as profitable as now when a lot of gpu miners join
I'm out. With the new GPU miner all cores of my server don't stand any chance. I'm sad because I like MMC very much.
