Microcenter has a really hard time selling AMD CPUs (everyone does, really) which is why they often give motherboards away for free. With a free board, an 8320e really isn't a bad deal. It's about as fast as a Core i3 in gaming, and pulls ahead in tasks like video editing. The downside is that it produces a ton of heat and draws a lot of power, which may drive up your costs if you feel you want an aftermarket cooler. With a free motherboard though, it comes out cheaper than an i3, and again, is faster in certain things.
What's the total cost of your bundle?
