PS i already bought the motherboard
As unfortunate as it is, can you refund the motherboard?
The FX series are very very old and pretty much dead by now.
It would be much better to invest in a Intel build or the newly released Ryzend for AMD.
If you cannot, get the FX 6300, a decent after market cooler and overclock it. With that you will probably be able to play non CPU-Intensive games with little bottleneck.
