I remembered in 2001 I bought Matrox Millenium G400 Dualhead Max AGP just to enjoy dual monitor with desktop spanning and games. It is really cool for multitasking. Nvidia and ATI technologies in multimonitor aren't that good at that times.

I work with graphic design, video editing and programming (php/html/asp) at most times and really need large and extended desktop space.

My next purchase would be another used monitor and dedicated GPU (low power) to drive the monitor. Seems if I connect 1 GPU to multiple monitors will force a GPU to clock faster to supply greater graphic demand even in idle.

Perhaps needs a better VESA table mount as the next monitor need to be rotated and easy management. My desk is has very limited space and different monitor types looks so ugly on the same PC.
