I am not a pro but i want a laptop which can be used for some professional use described above. Please suggest should o buy this dell laptop with 4200U or should i consider a 3rd gen intel processor for better preformance. Budget is 700$ for laptop.
I don't recommend the Dell laptop because the i5 4200U is a dual core (like all i5 in laptops) but it is specially designed for power-saving, i.e. for people who want a long battery life. I'd ideally recommend a i7, but for that budget you won't find one. Otherwise, try to find a laptop with an i5 that doesn't have a U or Y at the end of the CPU name.
