Todd Kopriva has this to say in the forum: Re: Adobe Premiere Pro CS5 5.5.2 update now available
I actually asked the same question at the blog site also as it's not clear the advantages of the Nvidia Maximus configuration. Thanks.
Here is what one of the Nvidia folks said when a similar question was asked elsewhere:
"That’s right; a Quadro 6000 and Tesla C2075 are not identical but they are very similar and you can expect similar performance. There are a few reasons you might want to use a Maximus configuration for Premiere Pro rather than a single Quadro 6000:
1. Having both a Quadro and Tesla GPU in the system means when the Tesla is cranking full-out on Mercury Playback Engine the Quadro is unaffected, so you can, say, open After Effects or other application that may take advantage of the Quadro, and system performance on that app will be better than if it was competing for resources with MPE on a single GPU.
2. In the future, we expect many users will want to run an animation application (using the Quadro) and a simulation application (on the Tesla) at the same time to provide animators with a level of interactivity they don’t have without Maximus technology. Example video is here. (http://youtu.be/_LagqqsVO28)
3. It costs less. A typical Maximus configuration has a mid-range Quadro (e.g. a Quadro 2000) and a Tesla C2075, which in that instance costs hundreds of dollars less than a single Quadro 6000 and offers similar performance plus the workflow advantage listed above.Of course, some users may want to run a Quadro 6000 and a Tesla C2075 and get maximum performance, but others can actually get the best MPE acceleration for less money with Maximus technology."
