If i was to order say the sapphire 5850 you think there is much chance of getting next week sometime seeing as OCuk currently don't have any stock (i know they have incoming deliveries).
I was looking to build this ASAP but i can wait for the 5850 but don't want to risk not getting any out of the incoming deliveries.
