Home office/gaming setup - Suggestions?

[Laszerus]

Basically my desk, and my home office in general, are a bit cluttered and I've got some money coming (not a ton, but enough) and was contemplating a redesign of my moniter/computer setup here, but I'd like some opinions/suggestions.

What I have now:
Gaming Machine
P4 3ghz
1gig DC-DDR400
36gig Raptor
9800 Pro
19" NEC FE950 CRT

Office machine/Chatbox
Athlong 2200+
1gig DDR400
40gig WD
Geforce 3
17" Viewsonic A75f CRT

What I would like to do, if viable, is setup dual monitors (LCD - probably with an arm) in my primary sitting position (atm one CRT is off to my right with a seperate keyboard/mouse) and have the ability to switch the second monitor between the office computer and as a second display for the gaming machine. I would assume a KVM is the best bet so I could also use one keyboard/mouse.

Is this going to be too severely detrimental to the second monitors (DVI) image quality?
Has anyone tried this and have an opinion on it?
Anyone tried any of these KVM's? http://www.newegg.com/Product/Produ...ange=1&bop=and&description=KVM&srchInDesc=DVI

Any opinions/suggestions would be appreciated.
