Thanks for the quick response. I'm going to trust that you're as experienced as you sound and go ahead and purchase the card. I'll post back later in another thread and let you know how it works in comparison to my GV-600. Sorry for the slight hijack... but maybe that answered the OP's question as well.

I'm very anxious to hear any personal experience in response to the OP as I'm looking to buy a 16 channel GV-800 myself and only use four cameras as well. I'd really like to know if those four cameras will reap the full division of the 120fps... meaning 30fps each.
