What is your top end of the budget like? Do you need any peripherals? Are you targeting 60fps or higher refresh rates?
At 1440p depending on the games you play you could get away very cheaply with an AM4 system, but your upgrade path will be limited. Also, are you looking at buying brand new or would you consider pre-owned?
I mentioned earlier on in the thread that I am looking at selling mine but I actually changed my mind - I am keeping the AM4 system for now. Maybe 2027 I will see what is available, since for my needs the 5900x and 3080Ti is still plenty enough for me, even at UWQHD@180Hz for the games that I play.
I think a nice stepping stone would be a 7800X3D and a 9070XT, but the RAM pricing kills any hopes or dreams that I had lol.
