Graphics card for video editing. ATI or Nvidia?

[vid83]

I am customizing a desktop and have two choices for graphics card in my budget:

512MB NVIDIA GeForce 9500GS [DVI, VGA, HDMI]
512MB ATI Radeon HD 4650 [DVI, VGA, HDMI]

Which is the better graphics card for video editing?

They're both decent cards, certainly fine for video editing. I'd go for the Nvidia as more video apps are going to be written to take advantage of CUDA, an Nvidia specific technology. Currently, you can decode AVCHD and VC-1 files with video card acceleration on Nvidia hardware.

I don't know if you'd envision using dual monitors in the future (nice to put your controls on one screen and your workspace on the other), but Dual DVI ports would be best for that.

I must agree with soopafresh as there seems to be more support currently for nvidia's h/w acceleration when it comes to video encoding.

but 2 important queestions remain:
1) Does that nvidia card have the hardware that will allow the GPU acceleration or is there another that would be better in that area in the nvidia line?

2) Is the software you are using for video editing going to support the gpu acceleration offered by the video card?
