I have a motherboad with one PCI-E slot which currently holds a decent gaming ati HD4850 graphics card, two monitors are connected to it which I use for work and gaming.
I want to add a third monitor (a old plasma TV with an DVI input for watching films etc.). Can I simply buy a pci graphics card with DVI out and use that for displaying images on the TV ?
Would this intefere with the other card in any way? and would it degrade the quality of the picture much if any?
For example I saw this http://www.alternate.de/html/product/Grafikkarten_PCI/Zotac/GF6200_passiv/275469/?tn=HARDWARE&l1=Grafik&l2=PCI-Karten
Is this ok, or could I go even cheaper considering all I want to do is to watch the occasional HD movie etc.
