I don't really mean to start a video editing thread... just wanted to post a tidbit that might help someone decide between the two GPU options on the W520. It's possible Adobe might push the Mercury Engine support back to the 1000M at some point, but I honestly wasn't expecting them to have included the 2000M. That they did -- and that it made so much of a difference -- was a pleasant surprise I thought worth sharing.
But to answer your questions... when Keith Combs wrote his mini-review
of the W520, he mentioned using Sony Vegas Movie Studio Platinum 10
. I'm not sure if that's CUDA-accelerated. I also found a NVIDIA CUDA video editing round-up
article over here, but haven't read it yet. Looking at their conclusions, all of these products are vastly less expensive than Adobe's stuff.
For me, I can finish this year's batch of videos on the 30-day trial, so despite having purchased CS5 as soon as it was released (about a year ago), I will hold off on upgrading. (The improved eBook workflow of InDesign CS5.5 is attractive too, so we'll see how long I do wait.)
