Looks like good spec PC for the money. I've heard good things about the 9800 GT card but I don't know about games so I can't advise you on that.

You might want to consider upping the Ram to 4 Gig and a second HD of 1Tb. The 200Gb HD is fine for the OS and Apps but if you are editing footage it's always best to have those files on a different HD. Also it's amazing how much space you need once you've got through a few projects.
