Where did you get your motherboard and graphics cards? I buy some things from geeks.com
I know there alot of nice cards out there now. I have found that on the UltraMon site they suggest you use
the same two cards when doing multi monitor setups. Thats why I went with two of the same Geforce FX5200 at the time.
They have been doing well for my ham radio stuff and for graphics and video editing I do some times on the system.
I have another system that is the same mother board and graphics cards for another ham radio station for working satillites.
my station is at http://www.hamradioclassifieds.com/kz4usa.html
