I didn' t buy a DELL, i bought a Toshiba P100-240.
Teh specs...
Intel Core Duo Processor T2400 | clock speed : 1.83 GHz | front side bus : 667 MHz | 2nd level cache : 2 MB
2048 (1,024 + 1,024) MB RAM| maximum expandability : 4,096 MB | DDR2 RAM (533 MHz)
160 GB HDD
17 " | Toshiba TruBrite WXGA+ TFT display
NVIDIA GeForce 7900 GTX 512MB
It came with XP MCE which is actually pretty cool, and i chose this " desk book" over the DELL XPS, Alienware Aurora (because i couldn' t get a hands-on with one) and Toshibas Qosmio G30 series (because they only come with GeForce Go 7600 and i wanted a 7900).
I have to say that for a laptop the P100-240 is REALLY impressive. It' s also good to know that my graphics card is superior to RSX!!!
Half Life 2 (including Ep1), Doom 3 and FEAR (the only games i' ve tested so far) can all be played on maximum settings, all getting 80+ fps. Even though it' s cost me nearly £1400 i' m extremely impressed with the performance. I' ll post some photo' s and screenshots (from games) on Friday when i' m back home (i' m in Sheffield playing ice hockey tonight).
The only thing about laptops that annoy me is the short battery lives making using them away from a socket pointless. Still, this thing kills my VAIO which is going to my girlfriend and it performs better than my desktop. I' m impressed.
