Bro I'm not sure you'd actually benefit from the 4K res. To really take advantage of that, you'd need the game assets to be of the same fidelity, which is rather unlikely. And using supersampling on textures has its limits too I guess. Right now, the safest bet would be to steer clear of 4K, and start investing in VR. From the reading I've done, it's about to become way more relevant than 4K res in the years to come. But you're welcome to argue, always nice to hear a fellow's views on the matter.
