this is a cayman/antilles rumors thread

Yes, you heard it right, some AIBs have Cayman chips now, and if everything else holds true to form, they should be on the store shelves across the world in 2-4 weeks. The kits come with a Cayman and some 6Ghz GDDR5, so the memory clocks will end up between 5.5-6GHz.
