I would like to turn an old xbox 360 into a gaming pc. My laptop doesn't have the power I need to run my new game. I realy don't want to go buy a new pc. From what I have read upgrading my gateway nv79 with intel core i3 processor wont help because I can't upgrade my graphic card. So A: can I turn my old xbox 360 into a gaming pc?(I don't need it to play xboxgames or live but it needs be able to get online.) B: Am I right about my upgrade opitions for my laptop?
