1. DUH! That's for OEM version of AGP card. They are at Overstock because they are virtually in closeout. I doubt if there are any of those being made now. 2. Good to hear the FX and NVS cards work together on one driver. I ran Nvidia and ATI together for years with no problem... but then, I didn't install drivers for the ATI cards, just let Windows XP library driver handle it. It's generally a bad idea to install more than one video card driver... especially if from 2 manufacturers.
Of course. If you are building a trading rig and know you're going to want 3 or more monitors, you should definitely plan on using Quadro NVS, Matrox, or something like PowerColor quad, or Appian.
