Was going to start a thread but this will do.
1. Power consumption is relatively low, actually much lower than you'd expect. Only 1 PCI-E needed
2. Performance, hmm... Not being able to say much at present, let's say fast ok. Current Driver still has no Async shader enabled, but still, GPU is fast.
3. Your distis should be able to place orders by the end of this month, so look for mass availability around mid to late June.
4. You should have 3 SKUs by the end of next month.
5. Could tell you more but then I'd be killed and I like being alive. It helps in a great many things.
