I would love to be able and see/use more options to accelerate 3D tools. If OpenCL gets better, I would be all in. 
OpenCL for example is in a few cases available in Blender and it is great to have it.
Roy Taylor is a really great salesman from AMD, he promised several times not only to Blender Developers but to many others who wanted to integrate OpenCL that it gets fixed for AMD cards.
Apple for example joined AMD in 2013 in the efforts to help with the improvement of OpenCL.
so there people can read and see that Apple and AMD are not laughing at Blender users but instead trying to get and keep customers.
Since the release of the article on toms hardware in 2013 there were some promising catalyst releases but recently two or three month ago the development with OpenCL products on both sides stalled and developers not only from Blender but from Furryball and other commercial tools have given up or put it on hold, the only renderer I know of which can use OpenCL is Luxrender and developers from that GPU renderer are also reporting issues with OpenCL;

AMD made something great with Mantle to get back into the horse-race and Nvidea now has to find a way to be equal in the gaming area.
the thing is, we as 3D artists, game producers, etc. have different needs on the Graphicscards and not always is a perfect gaming card on which AMD is really good at a good thing for us.
In general to everyone;
the Blenderartists forum has rules which are clearly forbidding quote battles and other issues;
http://blenderartists.org/forum/misc.php?do=showrules
it might be a good idea to apply those rules here whenever Blender is mentioned to save ourselves from flame wars or disgruntled Users 
nobody here wants to hurt Blender or its reputation we are past that and the best way to keep that, is to be as the rest of the Blender community as helpful to others as possible while producing great art.
some postings -everyone can have a bad day- shouldn’t be the reason to avoid a program or the people using it. <- generally spoken because it applies for Maya as for Blender and other programs and its users.
I was talking about those tips to get Blender working much faster, it should help in getting big speed ups in the Viewport.
First post has the tips summarised

I hope the offtopic route can soon be abandoned because both Maya and Blender deserve better.
