I ask because I haven't done it at all except for a brief hiatus with PTS and my trusty GTX 480's. I sold those and moved to a pair of 7950 Twin Frozrs that had been used for mining, but seem to work fine. My intentions were not and are not currently to mine with them.
So, if the guy before me was getting out... is now a bad time to hop in? And if so, what currency or pool is the "best" one to use?
Note: I pay a flat rate for power and only use my computer an hour or two a day, so let's assume that those aren't considerations.
