I recently built my first computer with some spare parts i had which included a nVidia geForce 5500 256meg PCI. My friend who recommended the card didnt know any better and told me to get PCI over AGP. While setting up my new Machine i noticed in the AMBIOS Setup that there was an Option of setting your AGP over your PCI or Vice - Versa. This gave me the idea of matching the PCI 256meg with a AGP 256meg Video Card. I was wondering how well the two work together? So will one card the Primary do all the work while the non primary just idles?
