    I have a pc with the following specs:

    ACER P5N-D Motherboard
    Core 2 Quad Q9650 3.00GHZ
    8 GB Ram
    1 TB 7200 HDD
    Windows 7 Home Premium

    Matrox M912 quad VGA video card running 4 monitors.

    at work i work on huge excel sheets and i would like to add a second matrox M912 video card and double the monitor count to 8. i already bought and set up the monitors and tried (unsuccessfully) to install a second matrox m912 video card. i attached a picture of the monitor setup i am trying to get to work. i could not figure out how to get the computer to recognize the second video card so i downloaded the user manual for the motherboard and while i am not sure, i think that the second video card wont work because this motherboard will only support dual graphics cards if they are both SLI-ready which i am pretty certain the matrox M912 is not. My question is this:

    1) is there a way to get the two video cards i already have to work?
    2)if not does anyone have any suggestions about what video cards would work? i dont need to game or anything thic pc is mainly used for excel.
    3) i was also thinking that since this is an older PC it might be cheaper (if kind of a pain) to get a different motherboard that would support two matrox m912 video cards and i could just swap over all of the components and sell my current motherboard. does anyone have any suggestions as to a motherboard that would work for this?
    thanks in advance for the help

    SLI is for gaming, you want SLI off if you want to use multiple graphics card independently for multiple monitors.

    Does the second graphics card show up in Device Manager?

    Have you tried the new card in place of the old card to see if it works or if its faulty?

    THANKS A LOT! it appears that the new video card i bought was defective. i feel stupid for not checking that before posting on here. i put in a random extra video card and was able to get it to work with my first Matrox card so i know 2 cards can work at the same time. i just need to get a replacement for my second Matrox card and i should be good to go. thanks for the quick reply
