    Installing/Running 2 Video Cards at once?

    I'm running a Sapphire Pure CROSSFIRE 3200 Advantage PC-A9RD580Adv (For 939) Motherboard, I got a Geforce 6800GT and recently bought the PNY Geforce 9600 GT.

    I was wondering if there was a way that I could make my two vid cards run as one, so succesfully combine them with Crossfire.
    I'm not gonna use them to like, install multiple screens, I'm really looking for a way to make them work together. I know it's a long shot, but I thought I might try here.

    Hope some of you guyz have the knowledge to help me, coz I'm a few braincells short to sort this one out myself :d

    - Thx in advance

    Welcome to TechIMO.

    Nvidia cards: SLI
    ATI cards: Crossfire

    You basically need 2 of the same model ATI cards for Crossfire.

    Same goes for SLI.
    So, you will NOT be able to combine your 2 cards together for better performance.
    Also, Your motherboard does NOT support SLI.

    Oh ok. Thx for the fast reply btw. So, if I would want to combine video cards, I'd want to buy a newer AM2 motherboard that has SLI capability, and get myself a second Geforce 9600, preferably from PNY too?

    I heard from someone today that combining cards would only give you like 30% more performance. Do you guys know if that's true and if it's actually worth it to do this then?

    That's correct. You need an SLI-Compatible motherboard with 2 PCI-Express x16 slots to run SLI. You also need another GeForce 9600. Doesn't have to be the same manufacturer, but that's the safest way to go. As for the 30% performance increase thing, that's not necessarily true. Really, it all comes down to what games you're playing. Older games are not optimized to take advantage of multiple cards, and thusly you won't see a performance increase.With newer games, you may see anywhere from a 0-100% increase in performance, although it'll typically be somewhere in the 20-60% range. As for the question about SLI being worth it: If you're an enthusiast in modern gaming, SLI offers a decent performance improvement over a single card, and is probably worth it. If you're not, you don't need SLI. Sorry for this massive block of text, by the way.
