Here's mine: I'm running MSFS with no problems and happy enough with it. To be fair, I have not visited much in the world than NZ, so none of the historically 'tricky' or 'heavy' areas that cause slow downs. And I do see some slow down when in very heavy clouds but **for me** it is still very usable. I fly only low-to-mid level (altitude) GA (so no complex a/c), usually only in NZ, and typically in real-time weather. I own a few add-on GA planes, and a few add-on NZ airports (ChCh, AKL, Queenstown, Nelson, Tairei).
PBTech Custom Build - Corsair H80i water cooler, Intel i5-9600K @ 3.7GHz, Kingston HyperX Predator 4x8GB DDR4 3200MHz, Asus Prime Z370-P II, Gigabyte GTX1080 8GB, EVGA SupeNova 750WG3 80+ Gold PSU, Samsung 128GB 840 Pro SSD, Samsung 860 EVO 1TB SSD, Seagate Barracuda 3TB SATA3, LG GH24NSB0 24x DVD writer black, Cooler Master N600 case, Logitech LS21 speakers, Win10 Home ... and a bunch of Saitek panels, TrackIR, cessna trim wheel, pedals and a desktop aviation parking break.
I run SPAD.Next for the Saitek gear, and REX WeatherForce for the ... weather.
So yes, it would work, but 'how well' --- well, that depends entirely on your expectations, type of flying, type of aircraft, additional scenery loaded, etc.
Flight sim really is a YMMV game...
