Even if Fury overclocks to 1250-1300MHz with voltage, it's still not going to beat an overclocked GTX 980Ti 1450-1500Mhz custom card, and it will draw a ton more power while trying to.
I'm sad to say that AMD hyped this launch way too much, and now the only real benefit of HBM is lower power consumption. The amount of memory bandwidth that HBM provides is simply not needed with today's games, and even when games/resolutions start too require this much bandwidth, 4GB of VRAM is not going to cut it. I hope that future drivers improve upon Fury, like they have with previous GCN based flagships.
