That Lenovo won't allow you to play games at mid/high settings. Find something with at least a gtx 750m.

If you are looking for a laptop: Alienware
If desktop PC it's easier and i would prefer to buy one ;D after having a laptop for 3 years and then buying a desktop one... well.. so happy with my new PC :D

You can try this one clicky you can add another gt 750m later which will gratly increase performance.

Woops thats the 650m model but there is also a 750m version

if you want a laptop for gaming you have to look out for somethings:
1- if it has the specs you need for the games you want. (obvious) ;
2- how it handles without the battery (you want a computer that can use lower power if needed);
3- how it handles in max performance ( if it overheats easilly);
4- be on the lookout for integrated graphics (that are rubbish for gamming and quitte common on laptops).
Look for this and other things on user forums and never on the websites and reviews, because their last objective is selling, users are usually unbiased.

My personal advice if possible is having a gaming high-end desktop for the games and a all-rounder laptop for work.

Try to find a Lenovo Y580 with 650M SLI.

what about the Optimus IV with a gtx 660m ?

There is no such thing as "Gaming Laptop".If you are going to play hardcore games, get a desktop.Laptops always cause problems and make you suffer !
