Extreme in every way. Only the AMD TRX40 chipset has access to the fastest consumer CPU in the world. It's no surprise to find that compliant motherboards start at £400 and rise to £900. At the extreme end of the market resides the aptly-named Gigabyte TRX40 Aorus Xtreme - an £830 monster with what the company calls unrivalled power delivery.

Those looking at this kind of spend will naturally also gravitate to the super-deluxe boards from MSI (Creator TRX40) and Asus (Zenith II Extreme Alpha) priced at £670 and £900, respectively. As we have previously reviewed both, this Xtreme can be compared fairly.
