Bossyfins :
They probably had to reduce the price already because of the 980 ti. While I can't confirm that, 650 seems pretty low for something with HBM.
Absolutely, that's the whole reason that the GTX 980 Ti was released when it was, about a month before the Fury. Nvidia basically told AMD that their new, expensive-to-produce Fury could only be sold for no more than $650. I'm sure AMD had the $1000 Titan X in its sights originally when it was thinking about its pricing. $650's got to be painful for them, but I wouldn't be surprised to see a price of $599 in the very near future. I just don't see these things being all that popular over the GTX 980 Ti.
And then you get reviews like this one from HardOCP:
The Bottom Line
The new AMD Fiji GPU and Fury X video card looks awesome on paper, but has underwhelmed and disappointed us when it comes to real world gameplay. The AMD Radeon R9 Fury X feels like a proof of concept for HBM technology.
In terms of gaming performance, the AMD Radeon R9 Fury X seems like better competition for the GeForce GTX 980 4GB video card, rather than the GeForce GTX 980 Ti. GTX 980 cards are selling for as low at $490 today. This is not a good thing since the AMD Radeon R9 Fury X is priced at $649, the same price as the GeForce GTX 980 Ti.
Usually trying to decide between two video cards at the same price point is a wash, with very even and split performance. However, this is not the case this time with the AMD Radeon R9 Fury X and GeForce GTX 980 Ti. There is a definite pattern that leads to one video card being the best value for the money, and it is GeForce GTX 980 Ti, not the AMD Radeon R9 Fury X.
Limited VRAM for a flagship $649 video card, sub-par gaming performance for the price, and limited display support options with no HDMI 2.0 and no DVI port. To be honest, we aren't entirely sure who the AMD Radeon R9 Fury X is really built for? The AMD Radeon Fury X is a confusing product, like a technology demo not fully realized, a showcase for HBM only but with no real substance. The AMD Radeon Fury X looks to be a great marketing showcase, but its prowess starts waning when you consider its value to gamers and hardware enthusiasts.
