Yikes, all of this news about the Amazon FTW pre-orders is nuts. Seems like the general consensus is a ship date of July 15th at the earliest.
The May 31st pre-order day was a bit of a disaster from my perspective based on my experience. The EVGA US site was getting locked up on my end to the point that it failed during several checkouts. Meanwhile my Amazon Prime alarm went off and I pre-ordered the FTW from Amazon as a backup thinking it would arrive mid June while still attempting EVGA US. And now all of this delay news.
In retrospect, I would have tried to order from Newegg more aggressively or attempted on multiple computers simultaneously.
I did a PC build in late April and put in a 4gb GTX 960 to hold me over until the EVGA 1080 FTW was available.
It seems silly to worry about this so much, however I have decided to go with a Gigabyte Xtreme Gaming 1080 from Newegg if it pops up before the Amazon pre-order ships...
