Nforce 780i compatible in 720 H2C

Hi, I own a XPS 720 H2C and im wanting to know if anyone knows if it will be possibe to upgrade the nforce 680i chipset currently used to the new nforce 780i chipset, which supports Tri SLI.
I have read that the 780i is very much the same board as the 680i  but with Tri SLI. If this is possible, how much of an headache will it be upgrading and adding another 8800 GTX, is there enough power connectors for an extra card for example? And is there room?
Any help is much appreciated.

    the only way one will upgrade a 680i board to a 780i would be to replace the board. one cannot just swap out the chipset. other factors have to be taken into account such as bus layout and such..
     
    So the only way for a 7xx owner is to wait and see what the next line Dell introduces..will it be a 7XX series which the majority are hopeing for as these system were supposedly "Upgradeable" or an entirely new line..only time will tell....

    If you want to go 780i,,just buy a new case with a power supply, motherboard, and swap your cpu, video card, etc into the new case.  of course you would not have a operational dell computer anymore.
     
     the new 780i chipset has  support for second-generation PCI Express, three-way SLI configurations, and its proposed Enthusiast System Architecture. There's a new reference motherboard design for the nForce 780i SLI, too—one that will work with Intel's upcoming 45nm processors.

    yeah but it only works on 8800 gtx and 8800 ultras. for some reason the 8800gt and gts 512s don't have the necessary second sli connector. even a 1kw power supply might get a little bogged down with three of those cards!

    All - According to nVIdia, the 680i is capable of Triple-SLI; see here. Specifically, the 680i LT does not support triple SLI, but according to the Dell Tech Specs (we all know how reliable those are), Dell did not use the LT version..

    Whether or not the XPS 720 actually supports triple SLI is another story.

    EDIT: According to the Dell tech specs here, Dell used the C55XE (versus the C55) version of the 680i which is the version needed to support Triple SLI (as eveident by the third PCIe x16 slot on the board. So, I would say there is a good chance Triple SLI would work in a XPS 720. Just get the third video card, the necessary connector and give it a whirl!

    well, some gamers probably would disagree, i have specs on dual ati hd3870, and the results were quite a bit better than a gtx
     
    but i agree , i cannot see running anything  faster than a gtx,,its a very fast single card solution..or the mighty expensive ultra.  i got a 8800gts, and it does okay

          Ultra, thats what I meant, not gtx.
     
        Yes, I'm running a gts now, and should have a new 8800gt tomorrow or monday at the latest to try. There is quite a difference in seeing 30/60 fps, above that I think is hard for us to decipher.

      Who would use it, SLI isn't that much netter than a GTX
