Otherwise, you need to determine which version of Encore you are using, and what specific GPU acceleration function in that version might be available to you.
That suite of Vegas will render to DVD Architect. From there you may build your disc menus. There is serious support for GPU-accelerated AVC rendering in addition to GPU acceleration for editing, video FX, transitions, compositing, pan/crop, track motion, preview and encoding.
Do not depend upon anything less than CS5 Encore to provide much GPU acceleration in any specific function you may need in your workflow.
Wow, thats a good deal for a pro card. That is what I would go with. I use a v5900 and its great, although Nvidia cards seem to be compatible with more software rendering. If you do decide to go the Nvidia route, go with a 4 or 5 series card with a 460gtx being the lowest I would go.
...take advantage of GPU acceleration for video FX, transitions, compositing, pan/crop, track motion and encoding. The series of test discussed below used an AMD FX 8150 8-core processor, 3.6 GHz, 8GB RAM, running Microsoft Windows 7 64-bit.
The benchmarks evaluated preview and rendering with OpenCL GPU acceleration enabled on the AMD FirePro v4900, V5900 and V7900 and compared to the comparably priced NVIDIA Quadro 600, 2000 and 4000.
Thanks everyone. For more information, I'm using Adobe creative suite CS5. Premiere apparently does just Cuda for GPU acceleration but I use Encore and Photoshop more. http://www.adobe.com/products/premiere/tech-specs.html
I found this article review of GPU performance and Adobe products. http://www.cgchannel.com/2011/03/review-gpu-acceleratio...
Here's a quote
my tests suggest that the Adobe CS5 applications run equally happily on less expensive consumer cards. The only exception is Premiere Pro; and even then, only if you are working with large projects.
With Photoshop, I feel that it is safe to say that any recent Nvidia or ATI card with at least 1GB of RAM is more than enough computing horsepower for all of the GPU-accelerated features, even with the very largest images.
With After Effects, if you are using the OpenGL preview renderer, any recent Nvidia or ATI card with 1-2GB of RAM should suffice, unless you are working with long compositions at resolutions of 2K or higher.
