Withough knowing where you plan to purchase and their costs, your intended use, and whether you plan to overclock, it would be hard to know whether this is a good build or not. On the surface, and knowing rough prices, you are on the cusp of your budget pushing you toward an Intel build. An i5 CPU will more than keep up with the FX-8320 (and push right past) and cost roughly the same. Motherboard costs CAN be similar to the AMD board depending on your requirements... Check out
How to ask for new build advise and give us a little more info...
Case - Good choice, but consider adding a third and fourth fan to supplement the single front intake and single rear exhaust fans.
SSD - The OCZ Vertex 4 is a great drive, however the Samsung 830 256GB drives have been showing up for well under $200 ($170ish) after rebate. Something to consider...
GPU - I tend to use XFX for their lifetime warranty, but any of those HD 7950 GPUs would be fine. Might want to check reviews on fan noise..
CPU COOLER - The TX3 is fine for a more quiet stock replacement. If you are going to overclock or are worried about heat, spend a little more money and opt for the Cooler Master Hyper 212 EVO or the older 212+. Both would cooler better than the TX3.
