[HELP] Macbook Pro for gaming

[CoCooN]

I wanted to know if the macbook pro would perform well for playing games like Counter strike source, CS: Global Offensive, Left 4 Dead 2, dota 2...

Pros and cons it would have.

13-inch: 2.5 GHz
Intel Core i5 dual-core at 2.5 GHz
Turbo Boost up to 3.1 GHz
4 GB memory at 1600 MHz
500 GB hard drive at 5400 rpm
Intel HD Graphics 4000

Thanks
