Well according to Reddit posts anyways. I haven't been following any of this and I remember reading an article about AMD outperforming Nvidia in DX12 benchmarks. I hope there isn't a thread about this already.

*edit*The short answer is that if you intend to buy a GPU for the next few years then you should avoid Maxwell as most games in the next few years will be DX12 and Async Compute is very important for perfomance. If you have plenty of disposable income and will upgrade in the next year or two when there are far more DX12 games then this may not matter to you but most people here are not in a situation like that.
I bought my GTX 970 with 4gb and dx12 written on the side of the box. It turns out both were wrong.

For Nvidia focused games I'll stick with my laptop (with a 970m), as it's good enough for most games right now (rocking Mad Max and MGS V on ultra without a hitch).
