I'm going to be away for the month of July and the place I'm going to won't have computers that I can play on. My budget is likely $1500, possibly $2000. If it can play games like Battlefield: Bad Company 2 or the Witcher 2 on Medium settings, that'd be perfectly fine. Portability is a bit of a concern, but only on the journey. Screen size doesn't matter that much to me.
