I'm about to buy a laptop, currently looking at 2 versions of same laptop. The only difference is CPU.
Laptop 1 has this CPU: 3317U (i5, 1.7GHz)
Laptop 2 has this CPU: 3517U (i7, 1.9GHz)
Is there any major difference between i5 and i7 CPUs other than speed? Is it worth spending extra 70 euro on second laptop?
