It's going to be at least £999 or a slim chance of something like £989 or £979 to pretend like they aren't taking the ****.
Look at the launch of Ryzen - $499 for the 1800x equated to £499 here.
Can you explain to me how you expect it to be any better with current pound strength?
You are aware the live rate of GBP vs USD is 1.30, as such most banks give around 1.26-1.29 varies depending on bank, but lets just say 1.29.
$999 / 1.29 = £775
So yes we do get it cheaper!
But of course it seems like every forum member here forgets about the UK tax, so add 20% back and your at £930, before any shipping, margins are added on. So yeah due to the weak pound whatever a product cost in USD it typically cost the same or more in GBP.
