FYI,
after 2.5 days of mining on Radeons at 425 MH and NOT seeing anymore confirmed coins come in to any rigs after more than 24 hrs, I decided to shut 2 rigs down in my shed because of heat etc.. and electric bill!

Now this morning I got up and went out and turned on those 2 rigs to check wallet, only to find I HAD HIT a block on my 7950 miner, so Its back up and running lol.  

I would say with Radeons, probably going to be lucky to hit a block per day  at your hashrate based on my experience.

I am dabbling with an old GeForce GT620, NVidia card I had lying around. Not sure if this card is capable of hashing or not? Anyone know if it will mine this coin?

PS: Note, the mining software all along had shown sometimes 2,500 blocks varies, mined at times on all machines,,, so I only really know I hit one 24 hours after the fact when I see a payout
