Opinion on My Low-Budget Gaming Build?

Hi,

I am a computing novice looking to build my first low-budget PC, for gaming. I don't have the resources to build a crazy, maxed-out system, but I'm looking for some decent performance and upgradability. I'll be running Windows XP Pro, because I have a lot of older games from the late 90's through the early 2000's, and I figure compatibility might be better with XP, and that XP will run faster and take up fewer system resources than Windows 7.

I am aiming for a sub-$1,000 system that runs cool and is relatively stingy on electricity consumption. Here are the components I have picked out thus far, which come out to a current price tag of $834.39. I intend to use a SSD as the drive containing the OS and maybe one game that I will play, and the HDD for storing the Windows Page File and other files; from what I read online, this can yield some performance benefits. Here are my components; any advice or opinions would be appreciated. Thanks!
