We've got 2 workstations with 4 1600x1200 monitors running off 2 (non-SLI) 
Nvidia cards (5200s and 6600s, I think) using the closed nvidia drivers, 
and it works beautifully. The plans are to increase that to 6 or 8 monitors 
as finances allow. We're using nvidia TwinView across the pairs of monitors 
on the same card, and then xinerama to stitch them all together.

If you want to go 6, I'd recommend you look at using a mainboard with 
multiple PCIe slots - I've seen them around with up to 5 now, which would
in theory allow you up to 10 monitors just using dual-output video cards.
I imagine that bus throughput must become an issue at some point, but we're
using Opteron mainboards (Tyan S2895s) and haven't seen any issues so far.

HTH,
Gavin
