Getting cold feet on 5090?

Hi, so I ordered a Asus Tuf 5090 on launch day last week. I’m now starting to get some slight buyers remorse and I’m wondering if I made a mistake? Kinda feel like £2,300 was too much money to spend on a GPU. 5080s are getting good stock levels and it seems they are better than initial reviews thanks to overlocking. I’m also seeing quite a few people say the Asus Tuf cards have bad coil whine.

Just kind of regretting making such a big purchase on launch day before I had all the information.

It’s probably another two months before my 5090 arrives. What do you think I should do? Cancel the order and just grab a 5080? Wait for the card to arrive and see what I think? Wait for it to arrive then sell it?

Thanks for any advice.
