Asus x99 a usb 3.1 vs asus x99 a II what's the difference?

[Derangerous]

They are the same price for me, and I was wondering if there is any key differences. Please help me?

Easy enough to compare. Go to the websites for each board and look for the differences.
X99-A II: https://www.asus.com/us/Motherboards/X99-A-II/specifications/
X99-A/USB 3.1: https://www.asus.com/us/Motherboards/X99AUSB_31/specifications/
You may find the differences are only in the layout and/or cosmetics. The latter is "prettier".

I've looked there and see then both, both but they are similar board but I don't See anything that pops out at me that makes me sway I've way or the other.like did they update something I don't See? What about those toggle switches they don't talk about. One is tcu switch, but what are those other two? And why they gone from the other board. They don't tell you about that lol that's why I am asking is thw a2 better and why

I'd say it depends on the cpu. The Asus A II is newer and supports the new 14nm cpus such as the i7 6800k. The older Asus A 3.1 supports 22nm cpus such as the i7-5820k. Whether this is changed due to bios updates etc I dunno.

What I do know is that while those x99 boards are fully optioned, nobody uses most of them. My z77 has TPU, EPU, mem-ok switches, also in bios. None get used. One is for software OC, one is Eco settings (on a overclocking board?).

So choose the board that DOES have the options you WILL use, looks acceptable or better, fits what you need it to do. Worrying over which board had or didn't have useless or undesirable options is pointless.
