17.3" Lenovo G700 (59378840) Intel Core i7 3632QM - Ivy Bridge Generation quad core CPU + nVidia GT 720m GPU and 1600x900 resolution for $700.
The GT 720m is a bit weak for a 1600x900 resolution screen in my opinion, but you should be able to play non graphically demanding games at medium graphics quality. You can also lower the resolution to 1366x768 when playing games for better performance. 1600x900 is better suited for multi-tasking than a 1366x768 resolution screen. I am looking at a new laptop because the 1366x768 resolution screen on my lenovo Y470 is too low to multi-task. I'm looking to buy a 15.6" laptop with a 1920x1080 screen early next year, but maybe I will settle for a 14" / 15.6" laptop with 1600x900 resolution...
