10900k vs 11900k - Music Production Rig upgrade

Looking to refresh my system. I’m rocking an i7-6700k and Premiere Pro and Cubase keep buckling under. Latency is way too high for me and I can’t seem to get it lower. Also have 64GB of ram and a Nvidia 1060. I’m trying to decide if I should upgrade to the 10900k or wait for the 11900k.

I’m curious becuase the 10900k has 10 cores and the 11900k will have 8. For video encoding and music production, I know it’s better to have more cores, but maybe this 10 core thing is BS.

Any thoughts?
