I Only have experience with Intel Processors, and was wondering if there is some kind of equivalency chart between AMD and Intel  Processor Power.  Is there?

yes

really, intel is still tops for gaming power... but if you are on a budget.. going with a 6+ core amd will still work fine (like the 6300)
