based on the assumption you might like to decode HD video quite regularly, then its seems pritty simple....

although i havent tryed one as yet, it appears the "8400 GS " is the lowest in the nvidia range that has the "VDPAU" hardware ASIC onboard, many people are apparently using that ASIC for AVC HW HD 720p and 1080i/p decoding with a multi threaded decoder like CoreAVC.

the ATI/AMD "x1300" while potentially can also HW decode if they ever get around to activating it in future drivers..., its not clear weather it has the ATI/AMD "UVD" HW decode equ of nvidia "VDPAU" HW decode onboard, so useing the "8400 GS " seems to be your better option right now.

while i do like the HD3xxx/4xxx and the potential for using ATI/AMD "UVD" ASIC, the simple fact is ,right now theres no documentation for it as yet, wereas the "VDPAU" ASIC is a known quantity, the developer docs are available and the 3rd partys are adding and improving "VDPAU" assisted HW decoding too open and closed apps right now.

as it stands now, it appears your "8400 GS /VDPAU" will be far better than your 2400HD inside the Atom 330 box were video playback is concerned.
