Thanks, I'm looking at a used octa core/16 threads E5 2667 v3. It has SSE, AVX, AVX2, FMA3. I can grab it for $300 CAD.
Problem with that is the LGA 2011 x99 motherboards and DDR4 ram is hella expensive. Total would be about 560 CAD.

Either that or I can grab a full refurb rig with i7 4790 for $340. Knowing more about the instruction sets required for the -m 15700, would you say that the 75% price increase of the xeon setup would be equal to a similar improvement in performance over the 4790 ? The cpuboss comparison is here: 2667 vs 4790

I don't have a 4790, but based on my experience with 6700k, I can expect around 15 h/s. The octa xeon hopefully does 22+

I have a 1070ti with 8gb and could not load the kernel without failures. If anyone knows how to operate the options to get it to work, I would be very grateful.
