I've been holding out for a second hand 5 series, but prices seem a bit nuts just now, e.g. there's a 5900x available on MM at £300 with next to no warranty when they're available retail at £30 or £40 more.
So, I'm buying today and it's a toss up between a new 5900x or 5800x3D. I'm gaming mainly at 4k 120Hz but dropping to 1440 if the game is needy in the grunt department. It feels like the 5900x with the extra cores makes more sense, particularly as it's less expensive.
Any final thoughts before I pull that trigger?
