That depends. It should be fine, but if you are running the 2060 or 2060 Super with medium or low settings at 1080p on some title where you are looking for super high frame rates, then it might not be able to keep up. If you are running medium to high or ultra settings, then it's not going to need to feed as many frames and will be fine. Overall, it should be fine, but keep in mind that BIOS updates and Windows patches have placed a fairly significant hit on the hyperthreaded performance of Intel processors. Not as much in gaming as in some applications, but if it's a game that is well optimized for multithreaded performance, you are likely going to notice it more. Unfortunately, not much you can do about it if you have a BIOS version newer than December of 2017, and you can't undo the microcode changes those versions bring with them so there's no going back once done, even if you reflash with an older BIOS as that won't undo the microcode changes AND it won't affect the Windows patches in any case.
Still, I think you're fine. Besides which, if you decide to upgrade down the road if you do have a problem, then you don't lose anything no matter if you chose to go with a 2080 TI super now. You really can't ever have a graphics card or CPU that is too much. Worst case scenario, you are limited to the performance of your weakest component and if your weakest component is a 7700k, well, it could be a LOT worse.
