Well, the 3060 is not exactly a card that's setting the world alight.
But your post said you're considering the 3060 Ti, which is faster than a 1080 Ti.
My personal opinion is that if you have a 1070 upwards, then it's only worth getting a 3080 or better, unless you really want DLSS or ray tracing now.
I'm running a 1070 at 3440x1440 and it still performs well.
I went for a 3080 at OCUK when they had "RRP" prices, but we all know how that went.
I'll look at the 4 series when they come out, and if they're available and not at unrealistic prices, I'll get one.
