New Laptop - i5 or i7?

[cmj]

I'm investing in a new laptop - Dell XPS 15 with 1080p screen upgrade.
Which processor is going to be better for use with Ableton Live 8

Core i5 560m (Dual core)

or

Core i7 740qm (quad core)

Price doesn't bother me, performance does. Don't want a mac tho before anyone asks.

Your help would be greatly appreciated.

Thanks,

Charlie.

It seems you answered your own question, get the i7.
