I7 2670qm vs i5 2430m

I'm looking at buying a laptop for gaming and portability. I found a sweet acer that has a NVIDIA 540m (very easy to oc) 4gb of RAM and a screen res of 1368 x 768? Or something close.

But it comes down to 2 processors.

i7 2670qm (quad core 2.2)
i5 2430m. (Dual core 2.4)

Both have hyper threading but is it worth it hot my gaming needs? Also ill be keeping this for a long time and yes I know the 540 isn't great. Any thoughts

Both processors will handle the games at mid/low settings in the given resolution.
But if you want to run more programs at a time (multi task) it is generally better to go for the quad core.

The fact is that your card will never get bottlenecked by both these processors for any game. So choose depending on the fund avaiable and the amount of multi tasking you think you will do.
