Thanks, the list was helpfulThe only real use for Userbenchmark is to see what BIOS revisions people are using for unsupported hardware, at least successfully enough to run the benchmark test. There are 110 reports of people using Xeons in Optiplex 790 systems, so presumably the microcode for Xeons is also included in the BIOS--which isn't unusual because they all come in a big blob from Intel so it's easier for the motherboard manufacturers to just put all of it in when flash is cheap enough to allow that.
