By the time it is out you will likely be on a 3070 which will be better than a 2080 anywayGood stuff, I’m pretty much there for ideal. I don’t think there’s enough between the 2070S and the 2080 to make much of a significant difference.
My only concern is will 16gb RAM really hold it back. As my 3600 at 4.4ghz is as good as 2700X anyway. Plus at 4K I am not sure if I will be CPU bound, but GPU bound again, even with 2080Ti performance or there abouts which I recon the 3070 will be.
