I've got some extra money, and am looking to upgrade. I'm relatively new to building computers, though, and have no idea where to start. As said in the title, this is primarily used for games (Tomb Raider, Bioshock Infinite, Total War: Rome II, Battlefield 4 when it comes out, etc...) Are there any obvious bottlenecks in this build that I should upgrade first? If there isn't anything (obvious), than just any suggestions for upgrades would be greatly appreciated. At most I'd like to keep it around $300 to replace a part or parts. If anyone has an extremely tempting suggestion, though, I could go up to around $500.

SHORT VERSION: $300-$500 budget, what should I upgrade?

I just got the PSU from the old computer also, will it support an upgraded GPU and/or CPU?
