Hey, the 13600k is an absolute beast, its completely underestimated by so many, but the ones who did go for it have never complained or been disapointed, and neither will you. It's really nothing like what has tradationally been considered an i5 model, its gaming performance is almost spot on identical to the 12900k.
And most B760 boards will be perfectly fine, i like mini itx cases so i can only speak from my experience, but i originally put the 13600k in a Strix B660i and it was rock solid, so if your budget allows, i would try get a Strix B760 if you want something guaranteed.
