that entirely depends on your budget .. if you can afford an i7 then that is great but otherwise an amd fx 8 core is a decent budget option ..
I will recommend an fx 8370 paired with something like r9 380 and a decent 550-600 watt power supply
or if you want a lower power draw option then fx 8370e + gtx 960 with a 450-500 watt power supply ..
I can't afford that. My budget is max $700-$750. Here's my build as of right now:

just some changes
get the 1866 MHz ram instead of 1600 ( optimal ram speed does matter for video editing ) ...
also you should get a 990fx mobo for a 125 watt tdp cpu like the 8320 or just as I suggested earlier get
an fx 8370e which is a 95 watt tdp cpu ..

and the 750 ti doesn't consume much power at all so you might even get a 400-450 watt psu ...
