Looking for a new laptop

Time is slowly but surely pinning down my laptop. So I’m looking for a new one. Will do some work with it, but it won’t be my primary DAW.
Is Asus laptops any good? I found this and according to specs it looks good:
ASUS A75VJ 17,3" 3630QM/GT635/8/500/BT/W8
and this:
Asus N76VJ-T4055H 17"
Any comments?

Also wondering… How big is the difference in performance between i5 and i7 on laptops?
