AMD FD8320FRHKBOX FX-8320 FX-Series 8-Core Black Edition
While $150 might be more than you're looking to spend, if your budget can afford it, this processor is pretty much as good as it gets. It's an eight-core model, meaning it can handle just about anything you throw at it. You can definitely save some money by choosing a less powerful option, but an eight-core CPU at this price point is truly impressive. It has a clock speed of 3.5GHz right out of the box which you can boost through some overclocking, though there are some better overclocking options out there. It has 8MB or L2 cache memory, and another 8MB of L3 to keep your system running smooth and fast. The only real drawback to this model is that it is at the high-end for a budget processor, and you might find it for just over $150 from some retailers so keep that in mind.
