I would recommend an Intel i7 with a decent graphics card, probably a Radeon series with at least 2gb of RAM for the GPU. RAM wise I would go 8gb+ at 1600mhz. Of course Intel is quite expensive, while AMD is a bit lower priced. I personally have an AMD machine right now and it runs all my games wonderfully. It depends on your budget and what kind of games you are planning on playing. Hope I helped, have a nice day!
