A photo of the XFX Radeon R9 390X box has been published by Reddit member crustyninja. The poster works at Best Buy and says R9 390X as well as R9 390, R7 370 and R7 360 cards were delivered today.
Best Buy's stock system currently has a stock date of June 21 for these cards and the pricing of the R9 390X with 8GB GDDR5 memory is $449, which is more than anticipated.
Our system is saying the price is 449 usd. In Stock date is 6/21, but that doesn't necessarily mean that is when it will be released.
Edit: This is Best Buy pricing and I cannot benchmark it, sorry guys.
Edit 2: Also received a r9 390, r7 370, and r7 360. Will post pictures and stuff later.
