Hardware Reccomendation for large project workstation

I am configuring a more powerful workstation build to decrease processing time for our larger projects.  I currently have an i7 7700k with 16gb ddr4 and a 1080 and it took three days to process our last phase one camera projects.  I am weighing the 10 core i7 vs a dual xeon setup and I cannot find a difinitive answer on the best setup to get and which xeon should be better than the other.   Will dual xeons allow me to process two at the same time better than one xeon or will getting a crazy amount of cores not speed up my processing that much.
