    Running video cards at x16 or x8.


    I plan on getting a Nvidia GTX 570, but I don't know whether I should get two or one, because my motherboard runs one at x16, and two at x8.

    Which would give me better performance?
    Thanks.

    I would recommend just buying 1.

    Its worth it having 1 running at 8x because it becomes a bottleneck to the other (i think)??

    Look in you motherboard manual and will instruct you where to install one card and where to install 2 cards. Do it their way. To use two card you will need a quality power supply, room in the case and great cooling. If you went to User CP at the top of every page and filled in your (My System Specs) it would help us help you. One or two cards all depends on your needs, wants, and money to spend. 16x and 8x is your Google home work for tomorrow.
