I have MacBook Pro 17" with 16 gigs of ram. I run After Effects on Parallels under Win7 because my main computer is a Windows7 work station and my CS6 license is for the Windows version. (the reasons are a long story)
Anyway, the MacBook is pretty good on everything in AE but Raytrace, because it has an ATI card. I am wondering if anyone knows if this device: Echo Express
Would allow me to get better performance on the MacBook Pro? I wonder if the Echo device would give the windows system and AE access to the GPU's processing through the Thunderbolt port?
I would ask the manufacturer directly. Thunderbolt is now just being built into PC motherboards so the biggest wall is proper driver support within Windows 7. As far as I know, hard drives and displays work decently but features like hot swapping aren't supported yet.
This, of course, is contingent on if Parallels is passing access to the Thunderbolt port to Windows programs.
