    Simply hitting high clock speeds doesn't always translate into great results. It's definitely a requirement, but Cuda cores are a big deal as well.
    GT 750M is a good example of higher clock speeds alone not delivering better results.

    It should be interesting to see what the next NVIDIA mobile flagship is going to look like.

    The 780MSLI should be faster than 1 GTX titan correct simply based on the specs, however, looking at my 3dMARK (fire strike) score, I'm doing about 1,000 less score, so can anyone chime in?

    CPU is a i-4900QM all 4 cores running at 3.6 GHZ

    There's already quite a long thread covering 780M versus Titan topic. Not sure what page it is on, but you should be able to locate it.

    Edit: it was on page 12, but I merged it for you.

    Be sure to go back at least a couple of months (last post was November) because there are a lot of great threads with good information in them.

    If you are using a stock vBIOS, the first step to take in achieve great performance from your 780M SLI is to grab one of the modded vBIOS from svl7. Stock vBIOS with NVIDIA "GPU Boost" does the opposite of what the name implies and cripples performance.

    does this require soldering? If so I will probably stay away... I smoke plenty of Ps2 trying to mod them with a modchip until finally getting it right.

    Nope, just firmware flashing. I've been using svl7 vBIOS mods for 580M, 680M and 780M. All of them run MUCH better with a modded vBIOS.

    can you post a link to download the vbios for 780m, I tried to get it form there forums but even after registering the site is not letting me download, it wasn't bad enough that they had an insane registration process.

    Out of respect for the talent and generous contributions that are offered freely at no cost to everyone, we do not allow posting of links to download svl7's vBIOS mods in this forum. They have requirements in place for good reasons and all they require in return is engagement and meaningful participation in discussions. If you want immediate access and the ability to bypass those requirement you are offered the opportunity to do so for a meager $5 contribution. It would be inappropriate and disrespectful to provide such a link.

    wow, such a long thread, going through for a night!
    Please gimme an advise, currently i'm on a m18x r1 with a setup of 2960xm and crossfire 7970m, but i had enough with AMD's driver so i'm gonna jump nvidia boat
    the problem is i cant choose between 680m sli setup vs 780m sli one
    680m SLI, i can get one set for around 800$ and pretty easy to find, but 780m SLI is different story, its hard to find and the price is around 1300$
    So the question is which one to get? note that i'm using this machine for pure gaming, not fancy 3dmark score, and i'm not interesting in OC, overvolt, mod... at all
    Thanks for reading!

    It's a shame you're not interested in any kind of OC. I'm not going to try change your mind and convince you otherwise but if that's how you feel go with the most powerful card you can get -which right now is the 780m/880m. It's hardly worth jumping ship from 7970m CF to 680m SLI if you're not OCing IMO ( I previously had 7970m CF). Performance is the same at stock. I wouldn't value nVidia drivers to be worth $800, even considering 680m SLI has better frame pacing.
    And if you own a 680m SLI it's hardly worth upgrading to 780m SLI if you are already overclocking just using 1 x 330 PSU.
    The easy hassle free answer is get a 680m SLI and OC the snot out of it.
    I hope that helps :D
