Good luck, have fun.
I posted the following in a separate post at ...
The AMD FX-8350 is most definitely the most bang for your buck. Under 200$, some motherboards cant hold it, but luckily mine could so i picked this baby up, performs like a beast, you shouldn't have any issues with it. At the moment I'm using a AMD R9 270x graphics card, if, again, you want the most bang for your buck, pick up a R9 270 or 270x and you wont have any trouble with any game. All recommendations/pointers if your interested in upgrading your PC, go crazy.

PS: If you decide to get a 270x or a 280, make sure you have a good enough power supply because they are pretty power hungry compared to the 270.
