^^ better to read reviews of users on
www.dell.co.in for both the models and then decide.
---------
Also, the heating problem is mainly due to improper ventilation (say, keeping a lappy on bed wich blocks the air outlet and inlet vents)...
-----------
But, yes if multiple users claim this feature of a particular lappy, then it has to do with the bad processor or lappy architecture..

Cheers n e-peace...
