Head-to-head against a Radeon R9 290X, who'll come out on top at 4K? It has been a little quiet on the high-end graphics front in recent months, and though next-generation hardware is on the horizon, we reckon now's a good time to revisit one of the most powerful GPUs of the current generation: Nvidia's GeForce GTX 780 Ti.

Launched all the way in November 2013, GeForce GTX 780 Ti still ranks as one of the best single-GPU cards going and commands price tags ranging from £450 to £670, with the latter representing liquid-cooled territory. There's a good choice of custom designs and bundles available from all the usual suspects, and the one that's going under the spotlight today is MSI's GTX 780 Ti Gaming 3G, priced at £500.
