    Gentlemen, points well made. A 780M may be on order in a short time, 2 is going to be hard to justify, but a single does indeed look like it destroys even Xfire 6990s ... so ... that's nice.

    Is a 780 the highest single I can pop into this thing ?

    And by that I mean does an 8XX series work. I know it has to be Mxm 3.0 compatible correct, or does 3.0b work as well ???

    Oh, another question. Do I need to alter the heat sink at all ??? Or does the standard heat sink I have from the 6990s work with the 780m or other ???

    @GodlikeRU has 880M SLI in his M18xR1 and he modded his 6990M heat sinks (soldered some generic aluminum memory or chipset heat sinks along the edge of the GPU heat sink). If I remember correctly, this was a matter of necessity because 780M and the correct heat sinks were not available where he lives. In your case the parts are easy to come by. The way the 6990M heat sinks are made they will not work right. The heat sink needs to cover and cool components along the edge of the GPU and the heat sink does not reach those components. 780M is actually a better GPU than 880M. It runs much cooler and overclocks a LOT better. The fastest, best and easiest route for you would be to grab GTX 680M heat sinks. They fit 780M like a glove and work perfectly. If Dell has them in stock they are only like $30 USD brand new and that even includes new thermal pads, support plate and screws. On eBay you'll generally pay twice that for used heat sinks. 7970M heat sinks will work OK as well, but you have to peel off the black plastic shroud glued to the copper plate. Not a big deal to do that if you cannot find 680M heat sinks for some reason. If push comes to shove and you can only find 7970M heat sinks, the part numbers are V4NXK (left) and 8J8TM (right).

    You can expect this kind of overclocking performance from just one GTX 780M: http://www.3dmark.com/3dm11/9522018

    Below is the information from my last heat sink purchase from Dell Spare Parts. The 680M heat sink part numbers and price are shown. Obviously, if you go with only one 780M, you'll want the left heat sink.

    The Maxwell GPUs will not work at all in the M18xR1. It will not boot with GTX 980M, so for the M18xR1 the 780M is the most potent option and 880M the option with the most available vRAM (8GB versus 4GB with 780M).

    Again fantastic info Fox, I will order heatsinks and not bother messing around with crap if I grab a 780m, and it looks like I might be ... just need final wife approval.

    10100 is pretty impressive for a single fricken card, the most I pushed with my duals was 8802 I think, which I was running in a -25 C environment, and which was pretty awesome at the time I thought.

    Looks like an 11% gain, over dual cards, which is kind of funny and awesome, especially knowing how hard I was pushing them.

    The tough call now is SLI 780s or a single.... leaning toward a single ... just because ? It will do everything I want, I really only play Diablo 3 and Dota 2 these days ... and both of those still work well on my single 6990... My main concern is that this card will fail at some point in the near future, and I don't want that to happen.

    And Crap, powernotebooks.com just let me know they only offer the MSI, not Clevo GTX 780m.

    There is one on ebay ... for 400 USD that was pulled from an alienware (the seller says he upgraded to 980) ... but I would much rather a new one ...

    Well, there is probably nothing wrong with that one, and $400 is not unreasonable. Find out if he is a member of this forum (user name) in good standing and if so you can see what kind of activities are posted here. As I am sure you already know, overclockers are a small minority, so chances are good that it had a pretty easy life doing mundane tasks like playing games. If there was anything wrong and he is a member of our community, I'd be willing to be you would find posts from that person looking for help with GPU problems. 780M is a really hearty GPU and I have seen very few examples of failures. The few I have seen have been mostly new GPUs that were DOA, but so far almost no examples of good ones that failed over time.

    That's why I had to buy GTX 880M because 780M was not available.

    Have you tried RJTech? Website seems down now... I think you should get the 780M quite cheap from RJ..

    Looking at RJTech they have the GTX 780m listed at $865. Seems a little steep :(

    GTX 970M only $450

    If you can't get 780M and don't plan overclocking then you can try to find 880M. I had to do that because 780M was even more expensive than 880M(!) in my country. I don't have heat problems because I don't overclock these cards, no problems so far.

    Hey guys, and Fox in particular :) So GPU 2 didn't last long, already dying. Running on the Intel 3000 ... which funny enough will run Diablo 3 and Dota 2, my main two games.

    Anyway, I am out of work right now, so cash is kind of an issue. 780s are pretty dang pricey from ebay (only looking for 1)

    What are your thoughts on 680 GTX, 770, or 880 ?

    I am guessing they will all work with an M18x R1 ?
