Hi, TE members, 
I am looking for laptop with superb clock speed, so that whatever application i run it runs smooth and easy for some years. Specially this, compiling codes and rendering at times I am sucked with present intel core 2 duo laptop 4GB Ram.
I am eyeing [ hp dv6 6017tx(6770) and dell xps 15(2GB GT540)] rest I dont find any good combination not in Sony till yet. Cant find any in Acer too?
Dell give the option of customization, but hp doesnt
, (correct me if wrong)
How much wil be the increase in performance?
1. i7-2720QM with 1GB GT525M (Dell custom)
2. i7-2630QM with 2GB GT540M (Dell)
3. i7-2630QM with 1GB 6770 (HP)
Wished I had option for( i7-2720QM with 1GB 6770 )
hyeah:, but forget that it is viable yet unless u go for Alien one's.
So far as cooling is concern, I believe both have good buildup, so heating will not be that issue.
64 - bit OS (windows 7 premium or professional) - how much will it differ in feature, will i hv major change in experience.
budget - 60K
Can increase it to more depends. I dont like compromising for few bucks. but not should be < 70k

NB:
If any software profs are here(working on EJB, SPRING, STRUTS, HIB) what laptops are u using??
