Client needs a PCI-e Video card that can run 5 monitors attached by VGA cables.  Windows 7
Card must be reliable.

Had a bad experience with  VisionTek Radeon HD 7750 Eyefinity 6 2GB
1.  VisionTek was unreliable with 25 foot VGA cables - monitors would disconnect, or connect with the wrong resolution.
2.  There was no correlation between the connector on the VisionTek and the Monitor ID numbers. The ID numbers were randomly assigned.

Thanks.

VGA is an analog signal and should not go longer than about 5 meters (16 feet).  Add the HDMI to VGA adapters you had to be using on that video card and I'm surprised it ever worked, at all!
What resolution do you need on the monitors?

25 ft + vga cables are not very good for signal integrity.
You should be using a booster device of some sorts.

Would DVI cables be better?

hdmi is probably a better future proof method.
What are you trying to do with the video?
You might want to look at something called digital signage.

Cables to go  had a booster  -  C2G TruLink 2-Port UXGA Monitor Splitter/Extender (Female Input) - 1 x 2 - 1920 x 1440

I am going to try that with shorter cables on each end, to eliminate the display card as the problem.
