With the imminent release of Visual Studio 2012, even if you do not classify yourself as a C++ developer, C++ AMP is something you should learn so you can understand how to speed up your loops by offloading to the GPU the computation performed in the loop (assuming you have large number of iterations/data). We have many C# customers who are using C++ AMP through pinvoke, and of course many more directly from C++.
So regardless of your programming language, I hope you'll find helpful these short videos that help you get started with C++ AMP
In particular the work we have done for parallel and GPU debugging in Visual Studio 2012 is market leading, so check it out!
