Which is better for video editing

[macrumorsMaster]

old ati Radeon HD 2400 XT with 128MB of GDDR3 memory or new shared nvidia 9400m 256MB of DDR2 SDRAM ?

I would think discrete is almost always better, but the nvidia is newer and I tested out an imac with the nvidia and motion seemed to work fine.

Thanks.

Video editing is not depending on the GPU, more on the CPU.
So both will do fine.

I once edited a DV encoded short film with my 12" iBook with a 32MB GPU, and it was not different to a better GPU. The CPU is used when rendering (if even necessary). Displaying video content is not hard to do for even a lower GPU.

Effects software uses the GPU more.
