So not expecting 1080 to do 4k at max settings? Big let down, the marketing certainly fooled me
In all honesty anyone who was honestly thinking that was going to happen, doesn't know a thing about the GPU market. Marketing =/= reality.
It's not happening. And I seriously doubt a single 1080ti will do the magic of 4k@60 for every game out today and in 2017. Wait, hell no, I'm
certain it will not. Because why would we then upgrade to anything else, ever?
4K is the new enthusiast benchmark, but it is far, far away from mainstream still. If anything, 1440p is slowly becoming the new mainstream. Especially because higher FPS is also getting into the picture and you don't just push 4k@120hz, but 1440p is reachable. High FPS is a growing niche, due to the new API's that drastically improve CPU efficiency it also becomes more and more attainable for a greater number of games. In addition, VR needs the high FPS as well - it becomes economically viable to build games and engines around a higher FPS target. If you're serious about your gaming, as in competitive in any way, 4K should be miles away for you, but 1440p@120-144hz is a very nice new sweet spot. 4K is also still plagued by a PPI issue which will move many users back to a 1080p or intermediate resolution. It either requires a very large panel, which forces you to sit further away and essentially lose the detail you paid for due to view distance, or it has scaling issues in games and with text, it being too small to read.
In addition, the 'other' new enthusiast benchmark is VR, which is, on average, 1080p x2 @ 90 fps. Most VR games run at lower resolutions internally to *hopefully* reach that magical 90 fps per eye. Nvidia uses technology (viewports), not raw power, to tackle the VR benchmark. 4K however, is where they have dropped the ball and this is not surprising, because the target market for 4K is fár smaller than the potential market for VR. Why would they cripple their release scheme of +30% per release on similar tier GPU, just to enable a small minority of the market (if it's 5-7%, I'd say that is optimistic)? They won't. Having the GPU do a little trick to enable VR, a far greater potential market share, is more than enough to create incentive.
The 980ti at stock clocks is probably going to end up within a +-10% margin of the actual in-game performance of the 1080 at stock clocks.
1080ti will probably be about 25-35% faster than the 1080. Do the math. You are definitely going to dip below 60 on multiple occasions at 4k. If you like to be optimistic, perhaps add another 10% from your 24/7 overclock, but I'd bank on 5-8% in-game performance from that.
