KuroiHane

Well, the final price was almost $120, but there's 2 day shipping (since I didn't know when he was going to travel here, had to get it quicker) and since I live outside the US, I can't do the Mail-In rebate. But still, much better than the near $220 a RM750x costs here and they perform about the same apart from noise apparently.

I own a Taichi too and I'm still trying to find out if my chip is "bad" as it reaches 80C with the stock cooler at 3.6/1.1875 (stock voltage). Gladly my h110i v2 does the job on cooling it.
 
1) They do get hot while overclocking, but the Taichi VRMs don't need active cooling at all. I live in a hot place (probably why my chip gets hot with the stock cooler) and I've never seen those VRMs hotter than 75C at 3.9 Ghz 1.38V. That is well within the safe zone for those components.
 
2)The Taichi has arguably the best AM4 VRMs, you probably won't need to worry about them even down the road with Zen+ and Zen2, assuming AMD lives up to their promise that is supporting the AM4 socket until 2020.
 
3) HWiNFO 64 manages to get all the readers from the board listed.
 

o alright so it's basically a no no

Ah, sorry it wasn't clear enough. I tried to make it as yellow as possible but I have so much in the OP it's hard to see
 
An 850W PSU can handle two 1080Tis and your 1700 OC'd (maybe wouldn't OC all three things but it's up to you). 
 
Good to know you don't cook your CPU daily  
 
Again though, you don't need 850W for a single card so don't spend your money that way if you don't plan to get a second card.

Watching YouTube, decided to look at the comments, scroll down a bit and find this... @Stefan Payne

Currency conversion is fun, ay? I'd say the TX650M would be plenty for you.
