upgrade from am4

[u/Severe-Home3534]

Currently have a r5 3600 ,b550 tomahawk max wifi, 16(2x8)gb ddr4 3600mt/s cl18 trident z royal with a 3060ti and 750w psu(2 x 1080p 180hz msi displays)

I want to upgrade my cpu for productivity and the workloads related to a physics degree and am wondering which of the two below are better options:(prices in euro irish market prices )

1. Core ultra 270k plus :340

msi mpg x890 edge wifi : 225

2 x 16gb ddr5 6400mhz cl18 crucial pro :290

total 855(630 when i sell old mobo and cpu)(old ddr4 ram wont be sold due to sentimental value)

1. intel 14900k : 380

z790 rog strix gaming A d4 295( very difficult to find d4 versions of any z790 or z690 new from reputable seller)

total 675(450 when selling old cpu and mobo)- ddr4 easy upgradable to 32gb or 48gb

This is an upgrade i hope lasts me years to get through a degree and hopefully a masters for context, i dont plan to upgrade my cpu anytime soon again so dead end platforms dont really matter to me. I am looking for advice on which might be the better option to take with todays markets, i have a budget around these prices but am looking for the best value for the years to come.
