Can i use an integrated video and a second video card for extended desktop monitors or do i need a dual head ?

Typically the moment you plugin the external card, the onboard video is disabled. Hence you end up needing two cards.



If you have an AGP system, you may have difficulty mixing/matching it with a PCI card (secondary display). If you have PCI Express, you may have better luck.



Dual-head cards maybe a better option.|||With an AGP system the video card will disable the onboard chipset.



With a PCI-e system I am not so sure.





However, I would recommend the dual head card because:



Onboard video tends to be cheap and crummy chips with little to no hardware acceleration. The GPU on the video card is going to be much better.



With different chipsets you will need two video drivers running at the same time. This is verboten under Vista and a bad idea under XP. You have no guarantee that the two drivers will play nicely with each other. A dual head card will eliminate this.



Dual head cards are the same price, or fractionally more than a single head card.|||wat u say?
