Been out the game for ages and last time i ordered the parts i needed to buy another cpu just to flash the mobo and get my purchased cpu working

Help me

I'd like to go for a 4080 at least. PC used for gaming and browsing only. Got a 4k projector and 1440 120hz monitor.

This is why i asked! thanks

Not sure what to do i think the pc is not long for this world, heard some very worrying noises from it recently under load. How long would i need to wait for new card etc?
