Video cards are really not that great of a deal with image editing but
to go out and buy some voodoo fx 16mb card. RAM is much more important
(as was said) as it allows more space for your image to be held. I
suggest buying two LCD monitors and a vidceo card that supports them
as photoshop is very frustrating to use when you have all the windows
etc up. With the second monitor you should place all of the windows
onto to that and use the first monitor purely for your image. That
is, if your really into it.
