I was wondering if a company like DELL ever made one that I could find on ebay for cheapYeah, I was going to say you don't often see HEDT K class chips in retail products. Usually just boutique builders. OEMs will use Xeons and ECC in that socket.
Another $150 or so for a motherboard and DDR3 ram for ~$50.
I don't see this being much better than a Ryzen 2600 you could buy brand new. 6 cores 12 threads and roughly the performance of Intel's Haswell or early Skylake, 4930k is Ivy Bridge based.
