I'm pretty much SOL once my UAD resources exceed 40%, no matter what PCI
latency I use.......and I've got another DAW just sitting here.......and AMD
XP 3000 CPU with 2G PC2700 DDR nd a system drive. All I need is a case, PSU,
a sound card and VStack. I have configured this machine in the past with 3 x
UAD-1 cards in the PCI slots without issue. Since there ar 6 PCI slots and
one of them was holding my Magma host cards, I doubt if I would nave much
problem running 4 x UAD cards. I just wonder if the PCI latency would be an
issue on this machine under heavy plugin loads also, even though it wouldn't
be hosting a playback application(unlessVstack could be considered a
playback app)
