A lot, as in people are over at my place almost everyday to watch shit/play games and we use the TV out (connected to my 29" flatscreen). Guess I have no choice

2 things I can do at this point are:
1)Install the AGP card, pop it out when I need to use the hi-end pc one
2)Buy a cheapo card that has at least TV out and can be installed WITH the onboard card
So if I had a PCI card, for instance, could I run both the onboard and the PCI at the same time? Connect the pci to the TV and use the onboard for game stuff?
