NewEgg is a very good online store. Both from a price and service standpoint.
That MSI GT660R-494US and its Core i7 740 CPU & GTX 250M CPU @ $1300 is OK, just not a great deal right now.
You get a lot more bang for your buck with ASUS G Series G53SW-XN1 Notebook $1200
Intel Core i7 2630QM(2.00GHz) Sandy Bridge CPU, 6GB RAM 500GB HDD 7200rpm 15.6" 1920x1080 LCD w/ NVIDIA GeForce GTX 460M
