Dell Inspiron 9400 or Toshiba Satellite P100

Hi folks, I'd like to hear your opinion between the 2 laptops below. Primary use as a desktop replacement, Photoshop and Corel Painter - illustration/painting with a wacom tablet. As far as gaming, I would also like to be able to play Half Life 2 with mid to high settings. Some of the key system specs:

Inspiron 9400

- Intel® Core™ 2 Duo processor T7200 (4MB Cache/2.00GHz/667MHz FSB)
- 17 inch UltraSharp™ Wide Screen UXGA Display with TrueLife™
- 2GB Shared Dual Channel DDR2 SDRAM at 667MHz
- 100GB 7200RPM SATA Hard Drive
- 256MB ATI MOBILITY™ RADEON® X1400 HyperMemory (Sales rep says the 256MB is discrete and can be upgraded to 256MB NVIDIA® GeForce™ Go 7900 GS


Toshiba P100

- Intel® Core™ 2 Duo processor T7200 (2.0GHz, 667MHz FSB, L1 Cache 32KB/32KB, L2 Cache 4MB)

The Dell is about 70 bucks cheaper.
