Well, right now it is a better idea to mine an alt coin like doge with a GPU, convert to BTC and then buy MMC on bter.com. If you had a R9 270x you would mine around 12 MMC a day, but could earn enough BTC mining an scrypt coin (like Doge or Kitteh) to buy 21 MMC. A 280x would mine 25 MMC a day, or buy 33 MMC from scrypt mining.
