There is even more to Windows 7 than that..
DX COMPUTE

"With the introduction of Windows 7, the GPU and CPU will exist in a co-processing environment where each can handle the computing task they are best suited for," wrote Chris Daniel, product manager for software at Nvidia. "The CPU is exceptionally good at performing sequential calculations, I/O, and program flow, whereas the GPU is perfectly suited for performing massive parallel calculations."
Microsoft is doing its part by putting DirectX Compute in Windows 7, so that developers can make better use of the GPU for tasks other than just graphics acceleration. Having the GPU pitch in where possible will help take the load off of the CPU so that it can focus on other tasks. The ideal end result of this is that the PC should be more responsive thanks to efficient use of processing power.
Daniel gives an example of how a GPGPU could speed up a task: "With new software designed to take advantage of this capability you would be able to copy and transcode (convert a video from one format to another – a very computationally intensive task) a movie to your MTP supported portable media device up to 5 times faster when using the GPU as a co-processor with DX Compute, as compared to only doing the processing on the CPU."
Microsoft also natively supports GPU acceleration with a new Windows Media Player and Windows Media Center for H.264 video content, most of which is encoded in high-definition formats and typically more taxing on the CPU.
"Parallel programming is the next big thing for the world of computing – it has started already," said Daniel. "DirectX Compute will accelerate this discontinuity by enabling massive parallelism to the masses. What we are talking about is co-processing— essentially using the right tool for the job."
