    I was thinking of purchasing a motherboard with two pci express x16 slots along with two pci express cards. Do you have to do anything special for dual video cards or would you just pop em' both in and do what you normally do?

    You will need a PCB connector.

    SLI requires two identical cards along with the sli bridge. The bridge usually comes in the mb package since the card mfg does not know what board you are installing to and they are not all the same size.

    SLI boards default to non-sil so you will need to set it to use sli. This is normally by a setting in the bios. Some boards may use a jumper for this also.

    IMO sli is little more than a gimmick. The technology is not new; it has been around since the old voodoo cards. Do some reading before you buy your parts since the sli board costs more and you have the expense of two video cards. BTW one 7800gt will outperform two 6800 cards and cost a little less.

    Why do you feel the need for dual video cards? Many newer video adapters support dual monitors anyway...

    By putting in a second mortgage on their homes, gamers can expect a whole whopping 2 extra FPS
    in their gaming system.

    You know...like when you gotta absolutely, positively, have to benchmark some incredible score with no discernable real world application in mind.

    Think something on the lines of "Overclocking Your CD tray".

    get one 7800gtx and be happy, sli is kind of a joke, or is it clever marketing????, they know some people just have to have more, more ghz, more watts, more ram, bigger hard drives, two cards instead of one, now some of those things have practical value depending on what you do with your pc, but two gfx cards has yet to make any real sense, unless youre just looking for bragging rights, and like has been said, the one guy with the 7800 is just gonna laugh at you anyway.

    SLI is great . . . but not right now. I made that mistake, I found that I can run any game out full graphics, everything juiced up, without any problems with ONE 7800GTX, but I bought 2 . . . this though, will come in handy when better more resource taking games come out, then I will be ahead of the game :)

    Just buy one 7800GT or X850 XT and you will be fine for now . . .

    It wouldn't work. Ati's crossfire is reported to not require identical video cards but as it stands now SLI still requires IDENTICAL cards. Cards from different manufacturers will not work together in SLI.

    As it stands now the best way to go is to buy a single 7800gtx if you want the ultimate gaming card. THEN when next gen cards come out and prices drop buy another if you want.
