I don't do a lot of gaming and I still know the 7800x3D is the chip to get for that. I also know the 7800x3D is great for gaming and not much else.
The reviews I saw said the 9000 series had a 10-15% uplift over the 7000 series in some production tasks. So... they are on par or slightly better? Ok. The 9950X was $100 more than the 7950X. If it had been $300 more I'd have went with the latter... but for $100 more I went with Zen 5.
10% better is what? $10 per 1% uplift? C'mon... that's a great deal.
I do a lot of video work... encoding... etc... as well as CAD rendering. The gaming I do is in 4K which is more GPU demanding anyway... but for the record the 9950X and 4090 benchmark in the top 1% according to 3DMark. I don't much care about losing a few fps to an x3D chip because in production tasks I'm much better.
