for VRchat and and other older games that are massively single-thread CPU bottlenecked, the 5800x3D is a game-changer. 
VRchat is usually CPU-bottlenecked, and in moderately populated instance you can see up to a 2x performance uplift vs. a 5950x, assuming no GPU bottlenecks. Image related.

On the flip side if your GPU is already overloaded ( low-end or just a ton of GPU-heavy stuff going on ) it won't make a difference. That is rarely the case in VRChat.

It's also your only upgrade path that doesn't involve paying for AM5 and expensive DDR5 ram, and even that will continue to be outperformed by the 5800x3D until the 7000-series x3D skew is released. 

tl;dr worth it unless you have a garbage GPU or plan to sell a kidney for the latest-and-greatest 6-12 months down the line
