With the VRAM discussion, you also have to mention that the 30x0 cards all have 60% faster VRAM than the previous generation (it makes the process of freeing up and writing to Memory much faster) and therefore will probably lead to a much smaller VRAM bottleneck than Turing had if you even encounter this as a problem, which most games so far don't even on 4K. 8-10 GB is still pretty good. But they'll probably release Ti variants of all these cards with increased VRAM, but also a much higher prices.
