I've just started building an x299 system, with a 7940X that should arrive next week.
This is gonna replace my work setup which currently are two old Xeon servers (database and file server), and I'll also get rid of my current main workstation which is a 6700K. Replacing 3 systems with 1, I'm really looking forwards to the noise and power reductions!
Really wanted to go with a Threadripper, but Handbrake seems to really like highly clocked Intels and that's one of my main workloads so nope. Doing much more HEVC than H.264 these days (4k videos), and my trusty 6700K just feels like dying when doing HEVC.
