Hello WR2, thanks for your anwser!
Yeah it seems that the HD 6370 is quite feeble to be considered for heavy gaming, also I've been researching more on HP laptops and have found nasty reports about common overheating episodes, even a friend of mine warned me against HP's laptops because of their tendence to die in a fireball without previous notice.
I have been peeking around other websites and found this lovely ASUS:http://www.idirecto.com/n53sv-laptop-asus-n53sv-core-750gb-p-52951.html
It has a higher price, but reviews state that it runs new games reasonably smooth, it doesn't produce a lot of heat, it incorporates a Sandy bridge i7 and a mid-range GT 540M.
I think this is a good option too, but I'm still open for suggestions.
Thanks in advance.
