Hi,
the 9xx series is rather new and is not supported by nouveau for now 
(modesetting is in 3.19rcX imho). Concerning acceleration: Nvidia needs 
to provide signed firmwares for those cards under a license appropriate 
to include in an open source project, until that happens, there wont be 
substantial improvements.
