600.00 is a fair amount of money but I'm sure if you are serious and you want a graphics based monitor you may spend a little more. Check out the base model
Lacie
It sells cheaper through camera stores such as Henrys.com.*note they come with calibrators kind of offsets the cost a tad.
I've been looking at it myself and using the specs to gauge other brands that are sold as multi purpose.
Be warned though if anyone decides on a Lacey make sure your system is up to snuff such as Video cards all relative info is on there site.
