i3-4130T vs i7-6700K

Solution
You could update the BIOS on your motherboard (if you do have a 6400) and use an i7 7700 (non k) and save a lot of money and not give up much performance. (If you have a z170 board you could still do the 7700k)



I really hate that site. Those are completely synthetic metrics that are meaningless outside of comparing them to the same metrics on the same site.
 
Well, you aren't wrong. But that is why i use it. It is good for getting an idea which will be better or worse and by how much.

 
i might get the 7700k but i plan to use air cooling i'm not sure if it will stay at a low temp as i'm on my computer all day for schoolwork games etc.

here's the fan i will use
Cooler Master Hyper 212X - CPU Cooler with dual 120mm PWM Fan

i'm going to get the 7700k if it will stay at low temp
i'm upgrading from i5-6400

my budget is around $850 for motherboard, cpu, fan, case, case fans if needed, and toolkit
found a motherboard that works with i7-6700k and fits the fan.
if you want suggest some motherboards, fans, and cases
