Need help finding a laptop

[sitheris]

I am looking to replace my MBP with a PC laptop whenever Windows 7 comes out.

My requirements:

15.4" Screen, Matte if possible
16:10 resolution (don't like the new 16:9 trend that seems to be going on)
3 USB ports
Wireless N
Gaming capable video card (must be discrete graphics)
Doesn't run too warm

Budget about $2000, can budge if needed

Any ideas? I haven't kept up with PC notebooks for a long time, but have been looking at the following:

Dell/Alienware
Sager
Asus

Open to suggestions on Models and other brands

Thanks
