Why lenovo essentials g505s (59-380146) not good good for hardcore gaming?

I will have the laptop mentioned above in a few days but on many forums i read that it can't run latest games inspite of its great specs or it gets hot like an oven even that it can't run gta 3. If its true then please suggest the best hardcore gaming laptop which can run latest games under 50k inr(indian rupees).

I have been using lenovo g505s with amd a10,2.5 graphics, 4gb ram and it is a fantastic laptop with which you can game amazingly. I play battlefield 4 on high settings and max resolution without lags. Please buy the a10 version and not the a8. Upgrade your ram by 4gb as soon as possible. Also update your bios to v2.05 as soon as you buy the laptop. This will eliminate extreme heating and shutting down of the system. I recommend you buy a good cooling pad too. You will not be disappointed
