This is probably something of a niche option for a budget processor, but it's too good to pass up without first considering what it has to offer. The specs on it are pretty barebones, but keep in mind it retails for about $70, making it a wonderful budget option. It has two cores and no hyperthreading, so it really is a dual-core model, and just 3MB of cache memory. It runs at 3.2GHz out of the box, which is definitely not amazing. However, what is amazing about this processor is it’s an unlocked Haswell chip with no manufacturer-placed limits on clock speed. Even with the stock cooler and basic power requirements, it's pretty easy to overclock this model up to 4.0GHz, and with better cooling as well as a very stable power supply, many people have tuned this model up to 4.5GHz. If you're an experienced overclocker working with a budget gaming system, , the value of this CPU cannot be overstated as it will deliver will deliver terrific performance at an incredible price.
