    So I am currently running my computer with the Nvidia GeForce 8600 GT. This is the older version of the card which IMHO is better than the new one which does not have two DVI-D outputs.

    Anyway, my Windows Eperience Index scores this as the loswet piece of hardware on my computer with a 5.5.

    I'd like to improve that score and I am wondering if I can do so just by running another video card in sli mode with the first one. Does anyone know if this will work?

    Also, does anyone know if I can run sli with the new version of the card? I'm only concerned because I know it has to be the exact same card to run sli and I don't know if there is a difference between the old version of the card (which I have, and the newer version). If no one can help me with that second question, I will try somewhere else to find out for sure.

    Thanks.

    It is possible that it would work, but I'd try asking in the manufacturer's (EVGA, BFG, PNY, etc.) forums first. If the updated card is clocked higher, SLI will limit it to the speed of the older card.

    You should be aware that doubling your video cards with SLI will not double your video performance. In specific, optimized applications you could see gains of up to ~70%, provided your system's performance is not limited by your cpu or ram. In other applications you may see lesser or no improvements. Unless you know the games or 3d applications you indend to run will benefit from SLI or you need improved performance in your current applications at higer resolution or AA settings, I usually don't recomment SLI. A single newer card to replace your current 8600 will likely provide more performance for your money than SLI.

    Get a new video card dude.
    8600's are flops. And you can only SLI the same card, and 8600's SLI'd are useless too. SLI doesnt really make that much of a difference unless a program is optimzed for it, and i doubt windows would need SLI to run better. And if your running an 8600 you might wanna check to see if your motherboard is even modern enough to have 2 PCI-E slots.

    the person who says you have to have two cards the same is incorrect. You can have different cards but they have to have the same GPU speed. My experience tells me aware that windows7 will actually let you run SLI on the motherboard you have, i would suggest you check it out with the manufacturer.
