It’s an xbox 360 elite I believe and he said it’s only 10 month old also has 5 games and 2 controllers

I’m thinking about investing in a new Macbook Pro (with 4 GB of ram) to replace my old PC laptop.
I would like to be able to make the switch but still be able to play all the games I have on my old laptop (Crysis, WoW, Half Life 2, Team Fortress, etc).
I discovered Parallels virtualization the other day and was wondering if it would be able to handle the stress of running both Mac and Windows, AND running any game I decide to play on it.

Does anyone know how good Parallels 4 is for this? And if there are better programs out there that could help me achieve what I’m looking for, please feel free to list them.

Thanks!

If it wont work, is it do to the graphics card? What specifically is wrong with the graphics card?
