Hi-
I'm going to build a PC that I will use primarily for playing Team Fortress 2 (developed by Valve using the Source Engine, like Half-Life games, etc.). I've been planning this build for quite a while now and have asked around in several places, but have gotten a wide variety of answers. You guys seem to be some of the most knowledgeable people on the internet, though, so I thought I'd ask here. I really don't know much about building PCs (I've never done it before) but I have an interest and I'd be willing to learn to make the best decision.
Here's the list so far. I'd like to get it <$700 if possible.

As I understand it, TF2 is a very CPU intensive game, and not so much GPU (but I don't really know that for sure). Because of this, I've decided to go with the i5-3570k which can be safely OC'd to 4.2 GHz. I also have selected the HIS Radeon 7850 2GB GPU, but I'm not entirely sure that's necessary for my purposes. I'm not really going to play games like Far Cry 3 or Crysis. Would a SSD be worth it? I have a laptop that I will use for most general use stuff, and I think it'd be better to have an SSD with the OS and some games on it when I first build the PC instead of getting and SSD later and transferring all of that stuff over. Like I said- I really don't know what to do. If anyone has other suggestions for this build, PLEASE let me know. Thanks so much!
Edit: I live near a Microcenter, Fry's, Tiger Direct, etc. Assume that's not an issue.
