Manju Hegde, Nvidia VP for PhsyX and CUDA Marketing and previously CEO
and co-founder of PhysX inventor Ageia prior to its Nvidia buyout, has gone to AMD.

While the tech industry often sees people move back and forth between
rival companies, this is potentially a big win for AMD, who are in need
of some big hitters to convince industry bods to adopt its "open"
physics and GPGPU technologies.

AMD has yet to confirm exactly what role he'll be taking at the company.
