The anti-AMD lunacy in this thread is breath-taking.
News flash. AMD is the one who has been giving more value for money than nVidia. All GCN Radeons (but especially GCN 1.1 and newer) will tend to be MUCH faster in DX12 than they were in DX11, since GCN was designed to for compute performance fed by multi-core CPUs running multi-threaded code. nVidia GPUs, including the current Maxwell, are designed to be fed by a single-core in serial. In other words, all current nVidia GPUs are rendered obsolete by DX12, if you'll excuse the pun.
Don't belivee me? Read this explanation by a retired AMD GPU engineer. This guy REALLY knows what he's talking about, he's no fanboy, he's an actual, bonna fide expert, his posts (go ahead and read through the thread and be prepared to be blown away) should silence the idiotic nVidia fanboyism on here:
