If you plan on gaming, your video card is going to hold back your system. (Although it depends on your monitor too, if you have a 15" lcd it won't really matter) I would recommend at least the FX 5700, if not the 5950 or the Radeon 9800pro. I think you can save some money on memory and just get one stick of the 512 instead of getting 1GB (if you aren't video editing, I personally don't think you need more than 512), I would like more opinions on that though.
