    Going to shamefully plug my own rig in this thread since i'm also gaming panaramic (5140x1050 @120hz).

    Here are some reasons to consider x79
    1. if you are on nvidia -- you will need x79 (or plx) for 3 way or 4 way SLI.
    2. 3 and 4 way SLI often get great scaling on triple monitor setups, especially on high settings.
    3. haswell and ivy bridge (z77 and z87) are handicapped for overclocking by intel -- they use crappy thermal paste instead of solder. x79 chips are soldered and this gives the best heat transfer. I'm expecting great things from the 4820k -- if you want to game with triple monitor, i highly recommend you wait until this chip is out before you decide what to build.
    4. 4820k costs less than a 4770k.
    5. quad channel memory
    6. x79 boards have been out a long time, you can probably find one cheap if you look around.
    7. x79 does run pcie3.0, it is just not 'officially' supported for sandy bridge-e. http://forums.guru3d.com/showthread.php?t=375347 I run pcie3 on my setup. It works. There is pretty much no reason why it wouldn't work, you do need to run a patch though (from nvidia)
    8. PCIE3 x16 is 5% FREE PERFORMANCE. you should never turn down free performance!
    9. i'm seeing gtx 680s on craigslist for ~300$. You can get 2 of these for the price of one 780 (new). From a price/performance perspective... the new gen is really pricey and you are better off sli'ing older cards for optimal price/performance... a 780 is what... 15% or something better than a 680? for double the price?

    One caveat -- some games are cpu bound on triple screens. (mmos seem to often be cpu bound, such as Rift, and Guildwars 2). In these games if i max all settings i end up with one cpu core maxxed, and my gpus underutilized. I can significantly boost my frames by lowering some cpu specific settings. Having 3 screens will tax your cpu higher than usual since there is alot more stuff to render. I find it worth it to drop certain settings (such as shadows in Rift, which are cpu dependent) to keep my game at or above 60 fps when the action heats up. I can leave all GPU specific settings maxxed. This does depend on the game.. some games utilize gpus extremely well (such as battlefield) and are never cpu bound.

    This is a good example.

    gtx 780's SLI'd = 120fps
    gtx 680's SLI'd = 100fps.

    Very simple, 20% performance gain (in a game which rewards gpu power heavily), which costs you $650 x 2 = $1300, or roughly 650 more than what it would cost you to build with 680s.

    is 20% performance gain worth 650$ to you? If you put that 650$ into 2 more gtx 680's (and your board was x79) your machine would be even faster.

    This is why x79 matters, it lets you run high end SLI configurations, and SLI is performance that is more cost effective than the current high end cards. If gtx 780's were 500$ a pop, this could be a different discussion... (we might just SLI those instead) but right now they are super pricey. The same argument could be made for even cheaper cards (such as the 670, 770, or 760). -- as long as they can SLI up to whatever card count you are targetting (some lower cards did not do 4 way sli for example).

    SLI will almost always beat out non-SLI, or lower card count SLI on a multi-monitor setup, because of this your goal should be to SLI as many cards as possible!

    Getting titans would be absolutely nuts, they perform not much better than a 780, and the cost is outrageous.
