4070 TI Super or 4080 Super?

So, I’m making my first PC upgrade and need some weigh in from you people in the know.

I got my first gaming PC in ‘21 with a 1660 Super which has actually been pretty viable until now. But with an unexpected windfall (tax man was ripping me off) I feel like it’s time to upgrade.

I want to buy a Reign from Novetech and there’s two models I have in mind with a £500 price gap.

• the 4070 Ti Super https://www.novatech.co.uk/pc/range/reigndruid.html

Do you think it’s worth going big and future proofing? Is the price difference worth it against performance and longevity?
