Well, the results you get with a GTX 1080, 35% isn't that big of a deal 10 ~ 30 fps at max difference.. depends on the overall frames and which resolution play at.
It's honestly all comes to the resolution you play at and 4k sound about like a sweet spot for 1080 ti. I see your point why you getting a 1080 ti
But, regardless.. if you have to money, then why not, right? We all want to have the best and the latest just because we can.
I hope you won't make a mistake getting the founder edition tho, even tho they showed the 2ghz oc on the stream.
Definitely wait for the aftermarket coolers and OC editions with more juice
Wait, what
3 games? FPS would rely on cpu more than gpu at that point
