A family member is buying a new laptop and wants me to find the best deal he can find, so I have worked everything out and am stuck on the CPU. The laptop will be used for Microsoft office, emailing and web browsing and watching series online, so what is better for that a pentium 2117u or a i3 3227u. I understand the i3 is better but is it really worth the extra price for this use and also this laptop needs to be able to last at least 3 years.
