Have you guys learnt nothing after the botched launched of the 3xxx series GPUs ?
You are behaving like those Apple cultists who camp outside their stores weeks in advance just to purchase another piece of plastic that will be available widely sooner or later.

If you get too excited about anything you're setting yourself up for disappointment.
