I'm answering your post because I'm not qualified to answer. That is, I'm currently in process of building a machine and researching what's best for me.
I used to have pretty extensive knowledge, even working for several years in the electronics & also computer mfg. industries, until I got hit with some strokes. Whatever I did know I sure don't now, so it's necessary to re-educate myself almost from square 1. That's my best answer because I want to save by building myself, and I want to know how Tab A works with Slot B for future troubleshooting & upgrading.
Therefore my suggestion is to spend some quality time scouring the web to edgikate yerself, here at Bleeping Computer, also Elder Geek, Tom's Hardware etc. and check out hardware comparisons. Be sure to get a good picture of who makes those comparisons, as in follow the money, because many are far from unbiased.
Find out why AMD made a major dent in Intel profits, what processor terminology means, like various speeds & performance measures, research particular technologies used by mfgr's. Then review what seems to work best for others, and equally important, what DOESN'T work for others
That last is often the driving force behind 'Incredible Super Amazing Stupendous DEAL OF THE CENTURY!!'
