If money isn't a concern, then get the M15x. It games like a champ, with a Core i7 toting Intel's most efficient power schemes for a product of its caliber. That GTX 260M is good enough for most games in medium-high settings. Also, in my opinion, the M15x looks better than the Studio XPS 16.
Gaming the GTX260M is easily a faster solution, but the HD4670 offers more features, but if you don't use those features they have no value in your decision, so for 'hardcore gaming' there's only one choice, for something equivalent in the ATi stable you would need a Mobility Radeon 48xx series.
Well laptops have their screen built-in. In terms of actual gaming performance you need to consider both the card and the resolution of the screen. Another factor is power efficiency of the graphics card as battery life is important for laptops.
Rememebr one trick for laptop gaming though, if you can divide the screen resolution #s by two on each and wind up with a good #, then you can get god performance without distortion on 4:1 pixel scaling.
