I would buy an Apple computer again! I don't really care that much for games, and PCs have a lot more game selections than Mac... so, I guess my answer would be "Neither"! LOL!
Well, you can buy a PS3 and get linux installed into it. The you can use it as a PC as well. Plus, the graphics will be excellent. Amazing what all the people without a life come up with. lol
PC forever,
Having a good PC means like having a few consoles.
And its easier to play using a PC sometimes.
