go with the i5-520m.
Why would he do that? If he wants performance he is right to get the i7 quad core.

i m not a kind of game freak..but want to paly atleast NFS Shift,GTA 4 ,Far Cry...
For gaming, a 2.4-2.8ghz dual might be better (depends on the game and of course the graphics chip)
Unless he's going to need four cores all the time in a laptop he'll benefit from higher clockspeed that the i5 provides.
I'd bet the best the i5-520M can do is rival the 740QM when running on 2 cores. It'll get beaten on higher core counts.
Or you could wait for the i5-580m 2.66GHz (3.33GHz turbo) which could be released in 2 to 3 months

Yeah, but how much will that cost? How much power?
Core i7-740 is based on Lynnfield right? This Core i5-580m is based on Clarkdale?
Maybe we need to take into account architectural differences rather than looking at just clockspeed?
i7-740QM is based on Clarkdale as well

CPU world article said:The Core i7-740QM is based on 45 nm Clarksfield core, which is built on Nehalem micro-architecture.
Clarksfield is the code name for an Intel processor, initially sold as mobile Intel Core i7[1]. It is closely related to the desktop Lynnfield processor
sorry lol glanced over that so quickly and saw Clarkdale instead of Clarksfield, doh.
