With everything but 3D (which is more of a gimmic anyway) Lenovo IdeaPad Y570 15.6" "Sandy Bridge" Laptop $1034
Core i7-2630QM quad core CPU, 8GB RAM, 750GB HDD, Blu-ray Combo drive, 15.6" 1366x768 LCD w/ GT 555M graphics.
Weighs around 5.95lbs (2.7kg) and measures .86" at its thinnest point, and features smooth metal shell and SRS Premium Sound and JBL speakers.
Since MMORPGs look much nicer on a large screen display you could get an external 1920x1080 LCD and use that for gaming (and school work in the dorm).
This 23" LCD monitor from Samsung also has a digital TV tuner for about $240
