I just went from a 1080 TI to a 3070 Ti myself, and I also was set dead set on a 3080 but gave up due to availability. I felt like I compromised, and the 3070 Ti would be temporary until I could find a 3080.
The 3070 Ti ended up being a huge upgrade in all my regular games for me. DLSS is awesome and makes a huge impact to frame rate with no noticeable loss of image quality to me. Both Cyberpunk and Control with DLSS and RTX on is sight to behold and runs much better than I ever anticipated at 1440p. I'm done GPU shopping for this generation and probably next at least as well.
I pwnz j00!
