As is, I think you would do ok even if not running all ultra settings, assuming this is a complete system you are buying and not picking parts to build your own, and price is reasonable for what you are getting. I’ll toss my thoughts out there anyway in case you are looking at picking parts.
5800x would be the last generation on the AM4 platform, meaning upgrading that at a later date would mean also upgrading the motherboard and DDR5 ram (if sticking with AMD, and possibly Intel). The newer 7000 series chips are out, with the X3D versions announced for release in a month or so. I’m currently looking and will go with the 7700x at least, which is about the same price as the 5800X3D and does well against it in benchmarks (even beating it in several). I’ll go with the 7800x3d if I can stretch the budget. There is the higher upfront cost of the mobo and RAM, but you’ll get great performance that will last much longer by having the option of a drop in CPU upgrade.
For the graphics card, I would try to go with the 12 GB version of the 3080 or better. Watching videos of it, the 10 GB version seems to struggle a bit at 4k unless you want to run at 30-45fps (which I personally don’t like due to fast panning jitters). The 12 GB version has more processing power on top of the added memory, and is the lowest I’d go. Ideally, a 3080ti or better would be needed if aiming for smooth 4k60.
I would also second the larger storage suggestion. I have a 1TB NVMe drive for everything but photos, and the sim is eating tons of space on it without having many add-ons. Thankfully it’s fairly easy to add storage.
For monitors, I wouldn’t specifically look for a gaming monitor for this sim unless you have other high refresh games you play. I’m running a 4k60 IPS monitor from LG and it’s been great so far (I got it primarily for photo editing).
This is perplexing. Do you mean Intel CPU vs AMD? If so, they tend to trade blows on which performs best. After the 5800X3D, the i5-13600k was the go to gaming cpu and was on my short wishlist of upgrades. Now AMD is matching that and the 7000 series X3D chips will likely blow them away again, so I’ve changed my mind. I’m sure Intel will come out and beat them with something else later. AMD does seem to be more efficient most of the time, but not always. I have an i5-8400 now but switching to AMD in part just for something different.
But all this doesn’t take into account your budget. If you are on a limited budget, I would say just buy the best you can afford, especially with the cpu. This sim is so resource intensive, anything less than some of the top tier parts will mean cutting back graphics settings to compensate.
