Worth upgrading my 4060ti to a 50 series?

2 years ago I managed to geta 4060ti 8GB brand new for 400 AUD. However, since then I have got a 3440x1440 240hz monitor and was wondering if it is worth upgrading. Ideally I would like a gpu that would last the next 5+ years easily.

The options I was looking at were the following:
4070 ti super ~ 1300-1400 AUD

4080 super ~ 1800 AUD

5080 ~ 2100-2300 AUD

I could also wait for the launch of the 5070ti in a couple of weeks. The games that I mainly play are mainly new triple A released. Also recently upgrade to a 9800x3d so I don't think a CPU bottleneck will be a problem.
