    Hi All,

    I'm currently completing my first new build in a long while (link to pcpartpicker list). It'll be a general purpose machine, for both work and gaming. I had essentially settled on the 5950x as my processor, but I also am a bit of a flight sim nut, and this recent review seems to show that the 5800x/5600x strongly out perform the 5900/5950 when PBO is turned on. The difference isn't small either; 10%+. Such a large gap doesn't really show up on any of the other benchmarks. So a does anyone have any ideas why the gap manifests so strongly for MSFS and not for other benchmarks? I'd have said it was the fact that all the cores are on a single die, but that's not the case for the 5600x which more or less matches the 5800x. Do the 5600x and 5800x just OC better than the higher core models? Any ideas on whether MSFS moving to DX12 might close this gap a little, or is >8 cores not really going to matter, even with that change. Thanks for reading guys.

    Best,

    That's for Microsoft to figure out. Any of the CPU's you've mentioned are more than adequate for any task you need to do. MSFS will get better over time.

    Certainly. I'm just curious if anyone had a guess as to why it manifested so much in MSFS but not elsewhere.

    MSFS is a weird train wreck that doesn't play particularly nice on any hardware combo it's not capable of taking advantage of more than a few cores. I would not buy a 6core CPU just for that. Perhaps the 5800X but if you were already set on the 5950 I'd go for that as you'll find it averages higher(though not by a lot)in pretty much every other game.
