I have been wanting to start playing WoW and CS:GO since my old pc died a year ago. I got an extra $500-600 for some new parts.. I still have a couple hard drives, case, mouse, monitor and have found some parts that I would like to try ..

I'm not sure if a extra 20-30 bucks for a little faster CPU is worth it. Last time I played wow I was on a AMD 3800 dual core CPU with an ATI 4800 512 getting like 20 fps @ 800x600 with low settings. So i'm not to worried about overclocking or trying to squeeze out a couple of FPS. I still have to save money for Windows 8.1
