Take a dual-core laptop with an i3-6006U or a quad-core Pentium N4200?

Question

laptops

I want to buy myself a laptop for the university, faculty of technology information. The choice was made in favor of the budgetary one, which would last for two or three years.
Here are the specs:
1. Asus X540NA HD (15.6" (1366 x 768 ) quad-core Pentium N4200 , 4Gb DDR3, 500Gb, w/o DVD, HD Graphics).
2. Lenovo IdeaPad 320-15IAP HD (15.6" (1366 x 768) quad-core Pentium N4200 , 4Gb DDR3, 1Tb, w/o DVD, Radeon 530 2Gb)
3. Lenovo IdeaPad 110-15ISK HD (15.6" dual-core i3-6006U, 4Gb DDR4, 500Gb, w/o DVD, Radeon R5 M430 2Gb Is
it worth it to overpay for i3, especially since it has only 2 cores.

Answer 1

For one core, i3 is better cpuboss.com/cpus/Intel-N4200-vs-Intel-Core-i3-6100U
But you overpay not only for the percentage, but also for DDR4. Although the vidyuha option with i3 is weaker than the second option.

Answer 2

Why not look at the flea market?
Syncpads are not even bad, plus their processors are head and shoulders above what you described
