Just updated from a 5900x to a 13900kf.
While the 5800x3D is still very good, it’s based on an “old architecture”. If you pair the 13900kf with DDR5, and all the rest, you have an advantage. Not a lot, anyway, but we’re speaking of excellence vs excellence.
Maybe if you want you can just wait February for the next x3D to come out. But this, of course, will imply changing everything.
