  1. will most motherboards be able to take ddr2 ram modules alongside ddr ram or are the old sticks no use once you have upgraded the motherboard

    No, they are completely different.

    Different Speed, # of pins, Voltage etc etc. The Notch is in a different place so you can't fit DDR into DDR2 socket & vice versa {though someone on these forums managed to & killed his motherboard}.

    The RAM is built into the Video Card, so compatability isn't a problem. You can use any PCIe Card!

    Some motherboards have two sets of slots so it is possible to run different types of memory - and some will even let you run both types together but they are rare. Look up the motherboard specs either on the paperwork that came with it or on the internet to see what your options are. Bear in mind that if you can mix the memory the system will usually default to the lowest speed fitted so it may not be a good idea anyway!
    Hope this is helpful.

    Differentiate Between GPU memory and System Memory

    Arran, as Fragrant Coit stated, this is a non-issue. The memory on the video card specs (DDR2) is memory that's attached to the video card and it doesn't care if your system RAM (on your motherboard) is DDR, DDR2, or DDR3. Hope this helps.

    thanks for the help that has helped one more question when graphic cards come with two outputs for example two div outputs or vga and dvi do they support dual monitor display.

    Usually yes - but don't take it for granted unless you have checked the spec!
