It looks like GPU stock issues in the UK are slowly improving—still a long way to go before being reasonable.
At the very least, I’m consistently seeing overpriced 5070 Ti, 5070, and 5080 models available, as opposed to everything being out of stock. I even saw the 9070 XT in stock for a few hours on Wednesday at £660 before eventually selling out.
Not ideal, but at least availability is trending upward!
