I thought about editing my post when I remembered it’s 8, not 6.
But I knew someone would remind me. 
Your point about FS2024 is well taken. We just don’t know anything, and any speculation is just that - speculation.
Still, there’s little doubt that a CPU upgrade would benefit me. I currently have the best AM4 CPU for FS2020. The question is whether the substantial cost of ugrading to AM5 (CPU, MOBO, DDR5) will be worth it for FS2024. I know I’ll make that leap eventually.
Never a bad time for more POWAH!
And there’s never a good time to decide on any of it because there’s always something new. You just jump on the belt when you jump.
It’s easier if you have nothing currently and just say I’m going to spend $XX and buy this.
I love MSFS more than I hate it. Even at top tier level there’s still 2020 things that happen. A lot of things happening this fall in tech and FS. It doesn’t hurt to upgrade, just depends on if its worth the hassle if you have everything happy and dialed in for just that little bit longer. There’s no magic melted butter perfect for 2020 though at any price.
For me upgrading to the 7800X3D would be just too expensive, new mobo, new ram and as I already play at my monitor’s max 60fps that would need changing too. Think I’ll stick with my 5800X at least till we know how MSFS2024 performs.
It seems the error was on my part, i set a custom fan curve and it wasn’t quite cutting the mustard when it came to catching the spikes, back down to 75 max on an air cooler. Room temp is 28*
I’m planning a whole new build for fs2024 once the 9000x3d chips have come out, been benchmarked, and priced. If it ends up being more than I want to spend I’ll drop down the the 7800x3d.
I would not assume they will sell out. You can still buy 5800x3d.
Yes, but it costs roughly the same as the 7800X3D.
I realize the CPU is not the only cost involved in upgrading to AM5.
But I’m thinking of grabbing one now and saving money for the other components. It’s a simple matter of gambling that it may go out of stock in a year.
Well if you move to AM5 can’t you just put a 9X series in there later?
Yes. But how long until 9xxxX3D series are reasonably priced?
Who knows, right? I mean, I started buying parts for my AM4 system 3 years ago, and only now is the 7800X3D at an attractive price point.
I could probably afford to build a 7800X3D / Taichi system with fast DDR5 within a year. Then upgrade the CPU only in a few more years.
Or I could just keep my AM4 setup chugging along and buy more planes. 
I would just hold the line until you see what 2024 does, may just be perfectly fine. Otherwise you’ll endlessly tinker with the ‘new’ on 2020 and still find things that make you crazy even if you get a 4090. Or, just keep flying.
‘Fine’ isn’t good enough.
I want MORE MORE MORE!!! 
There’s a reason the 7950x3d and the 7900x3d had those price cuts through months, they are not that great. For productivity you have better and also cheaper options. For games (in our case, simulator) the 7800x3d is better.
That said, and answering your question, I don’t think this is the ideal time to buy it. We have two moves being made: MSFS 2020 > 2024 and 7000 series > 9000 series. Although I don’t have high hopes, there are also the Arrow Lake CPUs from Intel.
If I had an AM4 right now, I would just buy a 5800X3D, save the rest of the money and wait.
Not even that, from all I’ve seen at higher resolutions the 5800X3D is no better than my undervolted 5800X, especially true without a high end gpu alongside (rtx3070Ti onwards).
Of course, you need to pair with a good GPU. MSFS works really well with the 3D Cache, better than I have expected. Even if you have a 4060, I would recommend that upgrade because of the frame generator + 3D cache. But it depends on how much would you spend to do this upgrade: 5800 > 5800X3D.
I only have an rtx3060 and although I can’t discuss them on here there are FG solutions other than a 4xxx gpu, of course it’s anybody’s guess if they will work forever. As mentioned I’ll wait for MSFS2024
I think the 5800/7800 X3D’s are going to take well to 2024. Whatever voodoo they’re doing to make the XBSX maximize it’s CPU performance it going to directly translate to those CPU’s with their all-matching cores and cache.
I never undervolted my 5800X, but I can say that upgrading to the 5800X3D (alongside my 3090 Ti) provided a quantifiable improvement in 4K performance. It wasn’t a whole lot, but it was a meaurable and repeatable 10-15%, especially in 1% lows.
Well that’s my point, 10-15% would be about my gain from (per CCX) undervolting and I’ve no 1% lows issues to speak of.
I didn’t know about undervolting when I bought it. Too bad…might have saved me some money towards an AM5 setup. Nah, I’m happy.
I think you will see gains beyond 10% on CPU bound scenarios, like a huge interenational airport with lots of live traffic. But again, it depends on the cost for the upgrade.
That’s as maybe but having a less powerful gpu means I’m never heavily mainthread limited even at big airports. I can only judge by what I’ve seen. My rtx3060 tops out at 2880x1620 all ultra, beyond that then data starts stalling meaning 4k native is beyond it however at 2k my system matches all the 5800X3D/rtx3060 combos I’m aware of. I have little doubt my fast ram helps but I still can’t see a reason to upgrade my cpu before I have new graphics.
