Keeping 1080ti and upgrading to 9950x3d/9800x3d build? What can I expect?

So after reading that Overclockers UK is expecting SINGLE DIGIT stock of the 5090, it’s looking pretty bleak over here and now I’m wondering whether it’s worth upgrading at all.

Another thing I’m considering is just ditching upgrading my GPU for now and just upgrading the rest of the system.

Right now I have an Intel 7700k which is really showing its age. I do enjoy gaming but I spend more time creating content. I think a part of why I don’t game nearly as much these days is the struggle to run AAA games in 4K without it looking like shit.

Will I face huge GPU bottlenecking here if I keep my 1080ti? Are there any other issues to take into consideration?
