hi I m trying to decide whether to go with an I5 8400 computer or I7 8700. I will use it for editing video. I looked up their specs and pricing. My question, is the price differernce of $250 really worth it? i5 is $550 and i7 is $800. I d like to get the most out of my buck and I am in a budget. It looks like i5 clock speed in boost is around 3.9 ghz compared with i7 4.3 ghz. how would this relate in rendering time?
