I was going to say wnat pmonett said, that you can get away with onboard video.
I do very little gaming as well, and i dont run the heavy duty games that require good vid cards, but i do use a 32 mb radeon agp card that can be had very cheap these days. I have another computer with a geforce 32mb card, same thing, works fine.
I have another computer that is using onbard intel extreme graphics, on another 21 inch crt monitor and its fine for what i do, just plain bus apps, net and email, small bit of graphics, editing still pics that is.
I have a 21 inch crt monitor set to 1152x864 at 70 hz with the radeon card and all is well.
Yes, i have 4 computers that i use all the time, lol.
Point is that you really dont have to spend a penny, or just a few dollars for a cheap card unless you are into heavy gaming or very heavy graphics.
Good advice + great people = tek-tips
