DVI vs Analog on LCD

[waynezo]

My system,
Athlon xp2400 cpu
Gigabyte GA-7vaxp mb with promise onboard raid controller
Kingston value ram 1024ddr pc3200 400mhz
Dual 80gig maxtor hd's 7200rpm ata 133 raid 0
Artec 16X DVD-ROM
Cyberdrive 40X16X48 CDRW
Verbatim 2.4X DVD+RW/R
ATI all in wonder 8500dv AGP primary video card
Radeon 9250 256MB PCI Secondary video card
Nokia 21" 445Xpro CRT Monitor
2 Hyundai 19" LCD Imagequest Monitors L90D+
Antec 430 watt true power ps
Ahanix platinum xp steel case
Windows xp home sp1
AVG Free antivirus
Kerio Personal Firewall

I am thinking about getting rid of my 21" crt and replacing it with a third 19" LCD. I have a visiontek radeon 9200 64mb pci card being fixed under warranty. Would it be worth it to install this as a third video card to have 3 dvi outputs? Or I could just hookup the third LCD analog.

How much difference does the dvi connection make?

All opinions welcome.

In terms of quality difference between a digital connection (DVI) versus and analog (VGA / HD-15) connection, from what I've seen, it's barely noticeable (given the same monitor and graphics hardware). To the degree that there is any difference, it's in the colors and contrast. Of course, to many, any difference is a big difference.

However, I also suspect that lower quality graphics hardware and/or monitors would make the difference more noticeable. I know that with analog monitors (CRTs), the quality of graphics hardware (and the monitor, of course) is an issue.

Here's a good summary of digital display technology versus analog display technology...
