A couple more options for you to look at:
Toward the lower end of your budget range: Dell XPS 15 "Sandy Bridge" Core i5 Laptop $800 w/ GT 540M graphics card
Core i5-2410M CPU, 4GB RAM, 500GB 7200rpm HDD 15.6" 1366x768 LCD w/ GT 540M graphics. You could save $100 going with the GT 525 standard graphics card which will do WoW & Sims3 on High, DAO on medium.
At the top of your budget (actually slightly over with taxes) but with everything you're looking for: Dell XPS 15 15.6-inch "Sandy Bridge" Core i7 Laptop w/6GB RAM & 1080p LCD $1044 w/ GT 540M graphics card and 20% off coupon.
Core™ i7-2630QM CPU, 6GB RAM, 500GB 7200rpm HDD 15.6" 1920x1080 LCD w/ GT 540M graphics.
The GT 540M is a mid-range graphics card but will handle the games you mention on High graphics settings and do a decent job on medium settings on more demanding 3D games.
It's also going to be great choice for animation & modeling programs.
You can play around with the options/features match your expectations to your budget goals.
A couple 14" models: TOSHIBA Satellite M645 14" Notebook
Core i5 2410M(2.30GHz) CPU 6GB RAM 640GB HDD 5400rpm Blu-Ray Combo drive 15" 1366x768 NVIDIA GeForce GT 525M w/ NVIDIA Optimus
(a version without the Blu-Ray drive should run about $900)
My recommendation at 14" IdeaPad Y470 @ $765
Core i5 2410M(2.30GHz) CPU 4GB RAM 500GB HDD 7200rpm DVD burner 15" 1366x768 NVIDIA GeForce GT 555M w/ NVIDIA Optimus
