About this price band
The £100 cap is where most UK buyers in the motherboards market actually shop. Independent motherboard reviews, filtered by socket, chipset and form factor. Every board is tested against the latest BIOS and benchmarked against the major chipset alternatives at the same price point. We only feature products with a live, primary affiliate offer, so every entry can actually be bought today. Prices are pulled from Amazon UK and refreshed on a regular schedule, so what you see here is what you will pay on the merchant page when you click through.
