Using the 17" MacBook Pro for two camera shoots

Just getting started using my unibody macbook pro 17 inch to do live interviews with two cameras and Boinx. I’d be glad to hear from other people who are doing the same thing. Hopefully we all could leaner from each other’s experience.

Especially the latest Core i7 MacBook Pros with AMD Radeon HD 6750M graphics are definitely capable of running 2 cameras with BoinxTV. I am running a 15" 2.2 GHz, the performance of that machine is quite amazing.
As of today I would still recommend the 17" machine for that use as it has the Express card slot for plugging in devices like Matrox MXO2. Thunderbolt capture devices are not quite here yet.
