@mos_8502 if your heaviest CPU workload is video encoding I'd suggest to populate only one socket with a high-core/high-frequency SKU. Anything in the E5 269X V4 line would do, those have high number of cores (16+) and high boost clocks (3.3GHz+). Given video encoding doesn't scale very well populating the second socket will likely reduce per-thread performance (because of the significantly higher memory latencies) and ultimately yield lower performance.
