I now have a working Asus W790 Sage SE tested with a W3-2423. For using it as a workstation board (I already have an Asrock with a QYFS for anything I need for XCC) would a W5-3423, a Q071 32C/64T 2.70-4?GHz (similar to 8462Y+), or a Q079 16C/32T 3.30-4?GHz (similar to 6444Y), or another ES I'm not familiar with be the best starting option?
The ES units are cheaper and would get me access to the NVME lanes, but not all of the PCIE.
The W5 is the bottom of performance for the WX-3 range and apparently has lower single-core performance despite reaching higher turbo speeds (according to Passmark results, at least) but has all 112 lanes available.
