If we are talking gaming, then, the vast majority of gaming development is going to be targeted at the most numerous available gaming platforms: the Xbox sX and the PS5. Both of those have Zen2 cores and a combined pool of 16GB ram. Comet lake gets there, rocket lake gets there, as well as all the Zen2 and 3 products. Gaming won't be a factor for another 4 years with respect to vote performance.
If we are referring to load times and the new consoles, then there's certainly a point to be made there, save for two factors: Comet Lake can support much more RAM than either console, and we know that caching is a thing. If you need more storage performance, it's possible to put an M.2 card in the second x16 slot in most decent motherboards and build a RAID array that can hit similar throughput numbers. It does get excessive, I admit, but it is possible.
In the end, it has ALWAYS been the case that single thread performance tends to improve each year. However, MT performance is still more tied to the number of cores and threads a socket can host, and the available thermal and power limits. A prime example is my current homeland server. I have a pair of Xeon V4 10 core processors with a bunch of ram. It's still got about the same throughput in most tasks as any of the 16 core thread rippers. If I wanted, I could replace them with a pair of 14 core models and keep up with the 24 core ones and not be too far behind the 32 core ones.
10 core comet lake won't be a major hamstring for many years.
