What is the best single-GPU graphics card available to gamers today? Technically, it would have to be the GeForce GTX Titan, whose unsurpassed muscle makes a mockery of most other cards and commands a wallet-busting £800 at retail.

The price alone has most die-hard enthusiasts looking elsewhere, but the good news for gamers is that the second-best solution - Nvidia's GeForce GTX 780 - is practically every bit as fast when a healthy dollop of overclocking is applied.

For this reason, add-in-board partners are fighting it out to produce the fastest/best GTX 780. That means plenty of choice, and with so much variation, we've set out on a journey to cut through the marketing jargon and identify the one GTX 780 that rules them all. EVGA's SuperClocked ACX, Gigabyte's WindForce 3X, Palit's Super JetStream, Asus's DirectCU II and Gainward's Phantom GLH have all been under the spotlight, but we're not done yet as we're now turning attention to Zotac's GTX 780 AMP! Edition.
