Don't really see the point of this, it's not really much faster than a 2080 Ti, and there aren't enough RT cores on either chip to make ray tracing faster.
If you wanted the fastest gaming card you could just buy a used 32GB Titan V CEO Edition with 128ROPs and 900GB/s of memory bandiwidth, flash it with a custom vBIOS and put it on water. I don't see a Titan RTX competing with that, as it would have a 33% memory bandwidth deficit and 17% CUDA deficit, in addition to the fact that HBM2 overclocks through the roof compared to GDDR6, 1.2TB/s should be possible on a custom vBIOS.
