The performance difference between the 8400GS and the X3100 is minimal...
If you want to game on a laptop, you need to spend ~2000$ if you want to play the latest and greatest games
Counterstrike: Source will not play very well on either, if at all (I know it can't be played on the Macbook, but even with the 8400GS being dedicated, I still don't think it can play it...and if it can it'll be low FPS <20 I'm guessing...)
And if you want real power, desktop IS the way to go for gaming.
