i have two computers sharing a monitor, keyboard, and mouse by way of a kvm switch.  i would now like to add a second graphics card to my main pc, and buy an lcd monitor.
the pc i want to do this to has the agp ATI All in wonder radeon for video, and is dual booting xp pro, and win98se.
my two questions:  can i use most any pci video card for the upgrade?  i want to keep the agp card as my main video source, but i remember reading something about the o/s wanting to use the pc card as the main source.
do you anticipate any problems with the kvm switch?  i want to mainly use the new lcd monitor, and of course would prefer to use the lcd on the kvm switch.
the second pc dual boots win2k and win98se.
