A lot depends of how much they produced this time, and how much they care about UK with stock. AMD did not have a great amount of stock on previous GPUs in UK, but supposedly they secured much more production capacity this time, plus with chiplets they are even less reliant on capacity of best process in TSMC, which means even easier for them to produce large numbers of these GPUs. Fingers crossed that will mean good availability AND pricing in UK.
That said, I applaud your approach to these things, we should never let corpo take us for a ride. One of the reasons my focus shifted almost fully from 4090 to 7900XTX now.
