Hi Joe,

I don't personally have any vista machines so I can't test this, or
vouche for how well multiple graphics cards will work under Vista,
others have got it work, but I don't know whether this includes frame
drops.  From your description it does sound like a driver issue.
Perhaps use the NVidia swap groups extensions might help solve this.

What I can say is that I've got a linux system with two graphics cards
and four monitors working on linux with good performance and not
hiccups like you explain.  So you could just dual boot your machine
and do a sanity test.

Robert.
