I'm kind of a newb to hardware so forgive me my ignorance(s). I've been using a Dell Pent 4 512RAM with (gasp!) WinME. It's used only for trading (on realtick platform), has never really crashed on me when it counted so I never bothered to change OS's. It came with Nvidia GE Force 2 Ultra w/64megs. I am currently using one 21" sony trinitron but would like to move my other 21" to the above setup. My vid card seems to have another open slot for a different type of monitor (looks like would fit squarish pins); can I use an adapter to make it fit my sony CRT, or do I need to get another vid card? Also, would I need to upgrade my OS for dual monitors, and if so win2k or winxp?
