Building an $800 gaming computer, need advice

[brucicus]

Hello,

I'm new to building my own computer and would like to figure out a build for a gaming computer at around an $800 budget.

Here's what I have to start with:
1680x1050 resolution monitor
2 creative speakers + subwoofer
microsoft laser mouse
Canon mp830 printer

I'll need everything else including Windows

And I'll be using this for games like Starcraft 2 and Civ V.

I'd appreciate any suggestions! Thanks!

Maybe this combo RAM/case since it's in the budget.
