    performance-wise sure, why not? just be aware that ull need a specific crossfire-profile for every and any game u want to play as opposed to "general" compatibility through the driver when just gaming on a single card ;)

    Why not adding another GTX 680m?

    Ah, ok! If it´s an order then going with 7970m crossfire makes sense. If he already has that laptop/ config, I think it would be cheaper going with a second GTX 680m. Of course, he can sell the single GTX 680m and then it makes sense again. But from my experience, I would take SLI and not crossifre ;).

    Just so you know I placed my order with 2 atis 7970m crossfire 5 days ago.

    After I placed my order I just check all over the net for my choise , full reading in forums,translate from German sites,PL sites, Swedish sites, all over the net...

    Even of enduro is off there are some major problems,mostly driver's side.

    Ati 7970m is powerfull card, 2 of them are über super duper,but , ....
    if they work correctly, if they don't heat up , if the drivers are good and if your cards are from a good production bash.And if ,IF, mother Ati want to support its sold out product.
    Yes they have sold (out ) , more than Nvidia.

    So if you choose to remain in Nvidia side, you have all the ifs,simply deleted, It's performing well and most of all stable in games cause of stable drivers, not so many fatal errors as hardware and you can have support by community members cause the problems you may face, they can simply fixed by options. they don't go hot as hell and you can also stable over clock em.

    so, my question yesterday ,was to my self, why I need this machine (p370em) ?

    I want it , to just score more in benchmarks/3dmarks/unigine bla bla and in real games to have throttling, high temperatures, unplayable games?unstable drivers? I answered NO,

    I want a stable laptop, cause its laptop and even if its Clevo there still remains laptop ,missing a lot of plug and play standalone pcs...

    so just before shipping I changed my mind and I changed my order to 1 single Nvidia 680m gtx.
    Hope I helped a bit, I am sorry just my personal opinion!

    Thank you.

    I already have P370em:)
    Buying a second GTX 680m is too expensive for me, besides my resseler takes my GTX and offers 2x7970m and I have to pay extra $ 100 for the cost of upgrading and because 2x7970m but is a little more expensive than the 1x680m,
    I think it's a good deal, because I'm using this laptop for three weeks, and my GPU is not new.
    I only worried about temperatures ( CF is hot in p370em) and micro shuttering in CF.
    Thank you for your opinion but I just want something more efficient, because, unfortunately, one GTX 680m is not as efficient as the two 7970m and SLI is unfortunately too expensive for me. In addition, AMD has a lot of drivers improved their games and most efficient is 7970m , 2x7970m is a huge different for one 680m i think.

    Then go for it :). As Jaybee pointed out, be prepared that crossfire needs more user-action. Updating or creating profiles, and so on. I had many black and blue screens with my 6970m crossfire setup, but maybe it´s not that worse anymore with 7970m.
    But I think I would go for it anyhow. ;)

    The 2 x 7970m for $100 extra is indeed a good value. :thumbsup: The biggest gripes have been with Enduro, but you won't be bothering with that with a XFire setup. Many of the other bugs that come simply courtesy of development are also improving, and 13.2 BETA driver is constantly being revised, so I'd say go for it.

    Guys and how about micro shuttering with cross fire?? The new drivers fix it or is standard issue sli/cf. I think 7970m crossfire will be more efficient than gtx 680 soc or 7970 ghz edition:) and finally question stock speed on i7 3740qm will be good enought for cross fire or i need overclock to 3.9ghz to have better performace??

    I don´t think that you will have much microstuttering. I never realized it with 6970m crossfire and sure don´t know with 680m SLI. As long as the frame rates are high enough, you´ll never notice that.

    The 3740qm should be enough for crossfire at stock clocks :).

    3740QM is the best value mobile processor right now.
    More than enough for you.
    And supports XTU overclocking (up to 4x I think).

    Yes you can take each of the turbo states (1, 2/3 and 4 core) up +400mhz which is 3.5 -> 3.9ghz for 4 cores loaded.
