I saw your earlier post - keep in mind, you can always send that laptop back.
The laptop will play those games, but on lower/medium settings and only 1300x768. The GT 640M "LE" version has a slower clockspeed than the regular (non-LE) 640M.
It would be alright, but i highly suggest looking into this lenovo Y580 deal thats going on today. http://www.logicbuy.com/deals/lenovo-ideapad-y580-gaming-laptop/40366.aspx
you get a much better GFX card, better CPU and more ram for under $900. If you want to upgrade to a 1080p screen it's only $1150, probably less than what you paid for that sony.
Sale ends today.
