Video and games put a great deal of stress on the CPU/GPU which creates a lot of heat as you have experienced. Download from the Internet iStat pro or Temperature Monitor. These applications will allow you to see exactly what temperatures and fan speeds the MBP is creating. You then can correlate this information with the applications that you are using.
There are internal temperature sensors that will shut the MBP down if they approach a lethal level. Theoretically using CPU/GPU intensive applications should not harm your MBP, though personally I feel that excessive exposure to high levels of heat is harmful to the MBP in the long run.
The course of action that I suggest you take is to install some form of cooling/heat dissipation device. I do not endorse any fan control device. I consider that a 'feel good' solution that really does not address the root problem.
My friend has a 13 inchMBP 2011 Model and i5 and 4GB and intel 3000 Graphics on 10.7.3(much Lower config than mine.), he runs the same game but no signs of over heating or lag in his mac, He even uses final cut pro but no signs of lag. and more over CS:GO is a very low graphic game. I tried resetting PRAM and many things, but no use at all
I think My Mac can handle these with ease its not happening.I already downloaded the istatspro its showing 60+. Any more suggetions thank you More Over my Mac is just 20 days old

From my vantage point I cannot provide you with the reasons why there are the differences that you cite between your MBP and your friends.
60c is not excessively hot. When the temperature approaches 100c or over, then I would be concerned.
The only way I can think of testing to see if there is a problem with your MBP is to erase the internal HDD and reinstall the OS. Then just add the 'problem' applications and see how the performance is. This way you have eliminated the possible influence of any adverse interference from other items that may currently exist on your MBP.
Obviously this is time consuming and you can decide if it is worth the effort.
I have taken My Mac to Apple Care.. and they the hardware test and it showed Fan error.. they cleaned the mac and gave it to me now fan is working fine.. and the issue was my fan was stuck at 2001 rpm and dosent increase when i use some high end apps, inturn my cpu gets over heated and my mac gets laggy and heated.. Now fan is working fine it reaches 4700 rpm when running high end apps.. Thus solved my problem..
I bought Cooler Master Notepal E1 for my mac.. and its an excellent product.. i ran many apps simply to test it.. Bottom of the Mac never got heated even on Facetime+Safari+Games No heating as cool as a closed laptop..
