  1. hey

    I have some planning about upgrading my computer

    as you can see on my sys-specs button the mobo is a ga-ma785gt-ud3h
    it do got 2 pci-ex16, but the second one only run at x4 speed.

    so i need to buy a new mobo to take advantage of the crossfire setup. and this is the mobo im thinking about.
    Gigabyte ga-790fxta-ud5

    this is the 5770 i have http://www.hisdigital.com/un/product2-503.shtml

    they don't sell the same one i have anymore for some reason, so this is the only one available where i'm gonna buy the mobo and the 5770

    as you can see there is a difference between them.

    will it work?

    If your buying a new MB only because the second PCIE slot is a X4, your making a mistake. you will lose only about 8% with a x4 slot and a 5770.

    Same card. Different SKU since one card has a dual DVI while the first card has a single link (single PCI slot). Otherwise they are the same card for all intents and purposes.

    EDIT: Some confirmation here

    Nope, you can CF cards from diff manufacturers even. those two will work great together.
