Yep - it the nail on the head. AMD gpu’s may not compete well at the 4090 level but they definitely compete with the 4080 on down - especially on price.
The 7800x3d is the king of the hill with regards to price/performance with MSFS 2020 and a lot of other games. If the 7900x3d is at the same price point then it should also be considered as MSFS 2024 is being touted by MS/Asobo as working more efficiently with multi-core processors. The extra cores of the 7900x3d may definitely come in handy for gaming and/or productivity - that’s why I got one (click on gamer pic to see PC specs)
