IMHO the Taichi is the same price and comes with wifi + audio AMP and supposedly better VRM components (if it's the Fairchild FDPC5030SG ones as on Fatal1ty pro)
Back of the board has doublers.
Also this confirms the Killer SLI is bad. It doesn't even have USB 3.1 gen2 , dual BIOS, or ALC1220, so for the $10 price difference to the Extreme4 it is really bad.
The VRM is at least $20 upgrade , audio is minimal (maybe $10) , USB 3.1 probably $15-20 based on add-in card pricing.
The Taichi is using Fairchild FDPC5030SG parts while the Extreme4 looks to use Sinopower SM7341EH.FAIRCHILD http://www.onsemi.com/PowerSolutions/product.do?id=FDPC5030SG

asdkj1740 , the ubiq parts might be what are used on MSI GPUs.
QN3101 high side , QN3107 low side seems to be what is on Zotac's GTX 1080 Ti amp
