Along with our recent editorials on why it's a bad time to build a gaming PC, we've been revisiting some older GPUs to see how they hold up in today's games. But how do you know how much you should be paying for a secondhand graphics card?

Along with our recent editorials on why it's a bad time to build a gaming PC (not least because of overpriced GPUs) we've been revisiting some older graphics cards to see how they hold up in today's games for those of you who have been eyeing the secondhand market. After retesting a series of older cards in recent months, we've been happy to learn that the GTX 680, R9 280X and even the GTX 760 still perform quite well in the latest games using medium quality settings at 1080p.
