    PC Troubleshooting - Seems I'm up for al nighter

    I started building this gaming PC like 8 months ago and today the final piece of the puzzle arrived... a 2nd HD Radeon 6870 to CrossFire it with the one I already got. But strangely, instead of increasing the performance, frames per second dropped by half on all the games I tested.

    I've troubleshooted everything I could think of... power, dust on the connectors, updated drivers from AMD, even changed the CrossFire bridge, still sucks. Now I'm gambling into blaming the operating system so I'm installing Windows 7, fresh install.

    My main reasoning here is that all the online reviews about this setup can't be wrong. Therefore, *I* must have done something wrong. Either that or I should change religions and jump on SLI bandwagon.

    I have a headache.

    does your mobo support xfire, or is it SLI only?

    is the second PCI-e slot wired for 16x, 8x or 4x?

    you want v-cards to be using 16x, but a lot of mobos will split them into two 8x links and some will run 16x and 4x only, unless you change it in bios.
    two 8x is fine.

    Otherwise, have you configured the driver settings?

    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    I'm afraid when you downloaded that "tassel twirling"site you put one hell off a virus into your gaming-puter and ruined it.

    Is this repair taking place on the kitchen table? With a spring compressor? Come on Rube, you've set the bar pretty high with some of your previous repairs, how about some pictures for us visual thinkers?

    The kitchen is for automotive repairs. Computer repair takes place in the bathroom, so that Ruben can sit and think.

    IIRC, there are lots of games that actually do far worse in Crossfire/SLI mode than with just a single card? But I am thinking about 5 years ago, so I could be 1639 generations out of date.

    In that case, I can skip the pictures than you very much.

    (go to tomshardware.com, post a message with information on your motherboard, video cards, OS, and how you are checking the performance.)

    You better fix this in a hurry. Those 3 extra frames per second are absolutely crucial in WoW.

    This has been golden... I got the rig properly working and I've been playing battlefield 2 all afternoon on 5760 x 1080 @ 120 frames per second. This is gaming heaven.

    So the question is ... what next?

    * A wireless gaming headset would be nice.
    * An SSD to speed up respawning
    * A mini fridge full of Red Bull?
    * A PROPER computer chair.

    So many choices...
