From my personal experience and other post I read online, the Richland 760k tends to overheat with the MSI A55m-E33..Find a good rated board to pair with the Richland...I actually build a PC for my brothers using the Richland 760k and its a beast for a budget. I bought them the parts in Euros with my Visa card (to us dollars) and I saved a lot.
Here is the build that I made, and used.

The only thing I would change from it is, the motherboard and instead of getting a non modular psu, is to switch with a modular..Get some cheaper RAM than the one I used...I got it on special..you can use something much cheaper than the overpriced shit I got..The case isnt so big and if you get a non modular, you might have a clutter with cables.
