Laptops for animation/art students?

'Ello!
I'm looking for a new laptop since the one I have now is slowly dying.
It's gonna have to be able to run programs like photoshop and corel painter.

I'm fully aware that a lot of people recommend macbooks for art students, but I'd rather not buy one, since in my opinion, they're simply too expensive, and I'm also a bit of a gamer, so I'd be happy if I was still able to play a few games (Like transformice or minecraft, not the newest assassins creed or dead space). There's also programs like SAI that can't run on mac etc.

I'd be overly happy if any of you were able to help me, so thanks in advace!
