No.... He posed the "What-If" for AMD launching FuryX prior to 980Ti release... If AMD launched FuryX @ $650 and only the 980 was out, it would still be a no brainer (assuming they still price cut like they did). FuryX is not worth $650 compared to a 980.
FuryX is about ~7% slower than the 980Ti. 980 is about ~30% slower than 980Ti. You are looking about ~23% difference between FuryX and 980 (and thats a factory clocked 980, not the 10% overclocked variants). But look at the price to performance. You get ~23% performance for 30% more money (and in reality, its probably about ~20% performance due to $500 factory overclock cards such as the Windforce).
Its all hypothetical really what he is stating, just saying..... Price to Performance would not be there IMo.
