the box was signed by an edgy asian dude at the conference, i don't think I can sell it as like new, although something like 8700k with triple 1080ti is attempting
Also I have a degree in EECS so i should be able to handle water and electricity at the same time
you would need to go to the i9 (x299) stuff for 3 way SLI. A non-HEDT cpu/mobo doesn't have PCI-E enough lanes. Also, Nvidia only offically supports 2 way SLI these day. (but 3 and 4 way still mostly work too.. but i'd not invest in more than 2.)
2 way SLI with a TI or a Xp is pretty amazing and will be faster.. by a bit, over the V.
Of course, the V is more than enough if you are playing 1440p. It is good on most game at 4k too. The problem would be the noise. I'd suggest selling that card You can still sell it on amazon as used - like new even with the sig on the box. (you could even say "new" and send it w/o the box.) Or put a Waterblock on the card. (then sell it a few month from now and buy 2 of the consumer versions of the new GPU )
