If you have 4k HDR, I would say yes.
I bought it mainly for the ability to capture clips in 1080p, but when I played Horizon Zero Dawn in 4k HDR the visuals blew me away. My TV is Quantum Dot and 1000 nits (super ultra HD) so maybe that makes a difference, but I suspect most 4k HDR TVs will show a huge improvement. With upcoming releases like God of War and Death Stranding, I�m sure the difference will be even more noticeable.
I�m lucky enough to soon have a highish end PC for 4k, so a PS5 won�t be on my horizon if it arrives any time soon, not that I think it�s at all imminent. I�m just desperate to get Steam up and running and back into Wreckfest. Can�t wait to see what it looks like in 4k.
