Knowing there a ton of tech savvy kilted brethren on this board, figured I'd ask.

Been looking at buying a laptop for school/work/home use. High end Graphics ability (ie. Photoshop), 3D Renderings, and CAD capable are musts. Somewhere in the $3500-$4,000 range. Work is paying for a large chunk of it.

Min requirements: WinXP 32bit, 17" screen, GeForce 7900+ or Quadro FX 2500+ graphics card (open GL 1.3 or higher capable), Intel Duo Mobile 2.0+ or AMD Optitron 64+

Been looking at:
Dell XPS M1710
Dell Precision M90
Alienware M9750
Alienware M9700 (AMD)
Sun Microsystems
Xi Computers

Anything else I should look at?
