3rd gen i5 vs 7th gen i3

Solution
Here's a comparison of the CPU's:http://cpu.userbenchmark.com/Compare/Intel-Core-i5-3427U-vs-Intel-Core-i3-7100U/m909vsm176913. I'd personal go for the i3-7100 Lenovo laptop, just because the hardware is more up-to-date and optimized for Windows 10. For day-to-day usage, you won't notice much of difference in performance.
