Fred,
It is funny that we agree. An article in the trade magazines, a few months ago, states that the color is better with an LCD and DVI. "They" (the experts) also claim that LCD should be used with DVI - and this does make sense (VGA is actually a conversion process).
In our case, I do not mind spending money on the computer - as long as it will work. Our current card is the PowerColor (ATI chip), 256mb, PCI Express. It was fairly cheap enough, as I remember spending lots more for the old Diamond Stealths (my favorite).
A 128mb, single port AGP card, should be fairly cheap. The boy's sports an nVidia 256mb AGP, and it was $49 from Newegg, six months ago.
PLEASE, if you get a new card, post your experience. Our needs are different from gamers and video buffs. This makes it difficult to get real-world results. (At least for us)
