Notes
We're comparing performance against the crazy-spec Asus Xenith Xtreme, costing 50 per cent more. And looking over to Intel as a platform alternative, especially as the Core i9-7900X costs about the same as the Threadripper 1950X we're using. Most pertinent of all, we're also looking at performance against the similar MSI board we reviewed recently.
