I 'might' be able to understand paying £1600+ for a GPU if you were getting Triple A PC exclusive games, doing stuff that the consoles are still 1 or 2 generations away from coming close to, but we're not. All we PC gamers now get are console hand me downs, running at higher resolutions, that are invariably broken and need 6mths worth of patching to get in to a fit & proper state.
There are simply no PC only development studios left to deliver the groundbreaking games of the past.
As it is, I can see this 40xx series launch being the worst Nvidia has ever seen. I don't expect these prices to last long, TBH. The poor (by Nvidia standards) sales will quickly force a rethink on them, I can easily see the 4080 16GB getting a quick price drop in the new year to sub $1K, the 12GB version going EOL to make way for its reintroduction as the 4070 at $699.
..even the 4090s are going to sell in much smaller numbers compared to the 3090, whose sales figures were skewed by people buying them during the mining craze, as nothing else stayed in stock for more than a minute or two.
