The 5k+ looks so much better to me than the 8k version, well regarding clarity anyway.
Will a 1080ti still be able to push solid 90fps in modern titles without turning all the eye candy detail down to zero, that's my big take on all this. It looks like the big selling point of 200FOV (Well 170 to be precise,) isn't actually all that great, way more demanding, introduces a ton of distortion at the edges etc. Most of us I guess will settle for the normal mode and the 5k as their simply is nowhere near the required amount of GPU power out there available yet to even drive these things how they need to be driven.
I'm so lost on what to do at the moment, I'm flip flopping between this and triple screens on a daily basis.
