Reply to Looking for new PC laptop. Dedicated video memory good/bad?

I remember seeing something about this on this board, but couldn't find anything about it in an hour of searching.

I'm in the market for a new PC laptop (Apple fanboy's need not apply), and was curious about the dedicated video memory. I currently use TP2, with my Kontrol S2, but am considering the switch to an S4, VCI-400, or Pioneer DDJ-SX in the distant future.
