You'll see little meaningful difference in games (the 5950x has better single core speed than the 5900x but the 5900x is already fast enough to not be the bottleneck in almost all situations). It might be more future proof though, there might be game engines in future which can properly saturate all 16 cores/32 threads. (Ashes of the Singularity is one that can now, but it's uncommon).

If you're compiling really large projects and want to cut those times down it could be worth it though.
