Yeah, for a 3050 it wouldn’t make sense, but if you got the budget for a 4090 then I would def. get a 13900K to make full use of it. The Fenix also loves CPU.
To be perfectly honest, I would wait 2 days to see what the ryzen 7 3d versions are like, they are expected to be the new gaming kings, overall, and double more so in MSFS. Even if you don’t want to switch motherboard etc. they may bring Intel prices down.
