GTS 450 useful for GPU powered video editing?

[Operandi]

I'm building a server for a client and have the opportunity to upgrade the GPU in his home desktop photo/video machine to a GTS450 I have sitting around. Right now the current card in the desktop is a very basic low-end Radeon 4000 series card which I would take out and use in the server and the 450 would go in the desktop. Dose the GTS450 have enough horsepower or do I need something bigger?

I'm not really sure how the video encoding process works in these editing packages. Is the entire process off loaded to the GPU or just portions of it? The CPU is one of the early AM2+ Phenom II X4s (920 I believe) and currently he uses Vegas Pro, though switching to Adobe is a possibility which is still the only package offering GPU acceleration correct?

if the software can not make use of the gpu, i dont think it has any impact on video editing.

I would think it was more IO based... meaning faster hard drive sector, with LOTS and LOTS of ram would be more prime.

i could be wrong tho... but im still leaning on its totally being software dependant, with more emphasize on the CPU then GPU.

I know Adobe Premier can use GPU acceleration, there are some tricks you can do to enable it on unofficially supported cards. Though I do think it is limited to nVidia (Cuda) and probably only Fermi which the 450 is. The 450 is pretty decent at folding for the budget mid-range card that it is so I think it would have enough useful power but again I’m no expert.

Well I found a similar thread and it looks like the 450 should work. Just have to make the switch over to Adobe.
