Which graphics card gives the most for your money

What the score is

The score is the same estimated performance figure shown on each product page, worked out from the shader count and boost clock, adjusted for memory bus width, on a scale of 1 to 100. Estimated from manufacturer specifications, not measured. Useful for comparing similar parts; actual performance varies by game, driver and system. Score per £10 is that score divided by the price, times ten. Prices are the cheapest new price we have today, in stock where any shop has it, before delivery; refurbished and used stock is left out.
