This will be my first time building a computer, so I'd like to run my choice of parts by you guys. If anyone with more experience can give some advice, it would be much appreciated.

Additional Comments: I have Windows XP 32bit, which apparently cannot handle over 3.5GB of RAM, which is why I've selected 4GB instead of 8GB.
And Most Importantly, Why Are You Upgrading: Because my current PC is about 5 years old, and I would like to be able to play games such as Skyrim, Natural Selection 2, and Starcraft 2 with acceptable frame rate (40-60).
Why don't you upgrade XP with it? The upgrade to 8 is only $40 to download and Microsoft is about to stop supporting XP if they haven't already. Also you'll be able to support more RAM with a 64-bit version. These are pretty cheap http://www.newegg.com/Product/Product.aspx?Item=N82E168... although I'm not sure if your site has the same offer.
