The only coins worth mining with a CPU are coins that can only be mined with a CPU. Look into protoshares (even though they're not technically a coin), memory coin 2.0 just released today, and there are a few other options in the alternate cryptocurrency section.

Why would you put something like IFC over maybe Stablecoin, Devcoin, or Digitalcoin. There are many more up and comers that I feel show much more potential than Infinitecoin, it's only a matter of time before at least 1 of those 3 make it close to the top.
