Using the newest Macbook Pro 15" with 512 of vram and 4 Gb sysram, would a small external eSata raid array....like the LaCie little big disk quadra, be enough to do triple screen projection with multiple HD (up to 1080p) clips, some effects/renderings, also including a live stream?
And one step further, would a SSD hard drive in the laptop also increase performance...as having the clips over a very fast (eSata) connection and only burdening the hard drive with program work would seemingly be a screaming solution.
