I'm surprised that no one is taking pre-orders for them yet.
Same here. I'm kind of in a "Catch 22" situation. I was about to purchase 100 x MSI 390 GPU's until I heard last night about the AMD RX 480 with 14nm chips coming out June 29th.
Especially, since no one is taking pre-orders on them, I'm wondering if there will be limited quantities that will limit retailers to 5 GPU's per customer at first?
