    I'm wondering if it's worth the upgrade.

    Not worth it, you have more cores and better RAM bandwidth = faster. IB is about 10% faster clock for clock, Haswell is about 5% faster than that, but with 50 GB/s vs 30 on the RAM and and 2 more cores, you're fine as you are, plus the extra PCIe lanes SB-E bring.

    I guess we're all find out in 3 weeks time for sure

    However if I was to guess I would say in environments of very multi thread aware applications SB-E would be far and out right better. That being said in instances where applications or games that aren't so multi thread aware then Haswell will out perform SB-E, throw in some Overclocking and who knows, it depends on how well Haswell will perform Overclocking wise.

    If you using applications that require lots of threads, or can simply make use of those threads stick with what you have because I can't see Haswell outperforming a 6 core at what a six core does best.

    But like I say, we'll see for sure in the next few weeks :)

    I say no way. What you have now should do more than enough for quite a while. Not worth the cost of another mobo,and ram too. I just bought the Rampage Extreme x79,and the 3930k as a bit of an upgrade of my existing set up.

    There is no final confirmed review, what you are quoting are the notoriously unreliable Chinese websites.

    At the OP: We have no idea, wait a month.

    As a comparison overall, my CPU (980X Xeon), is still faster than a 3770K due to the extra cores, extra RAM bandwidth and overclocks just as well.

    The bandwidth should be about the same vs 1155 maybe a tad slower

    OP Do you have any overclock on your processor and if so what it is it? The only good thing that we know if it is indeed true is the awesome overclocking that they got out of the Haswell processors. Other than that we really do not have any official benchmarks. Also you have a 6 core processor for that reason I would not upgrade to Haswell.

    But I mostly play Wii and PS2 games with Dolphin and pcsx2. Are these emulators thread aware?

    uhh...does your SB-E and 680 struggle with Wii games?

    We won't know for a while for sure, but I expect you might be gaining a slight advantage while gaming (and only certain games), while throwing away a huge advantage with highly threaded tasks.

    You'd pull less power doing it though.

    I would upgrade if I were you. A qx9650 at 4ghz bottlenecks a single 580 in my backup rig. 2 590s are highly bottlenecked.

    Who said anything about a QX9650? That's what, 4, 5 generations old? The OP has a 6-core SB-E 3930k with far better performance than a qx9650...

    Sorry TK, I just assume posts are directed at the OP unless otherwise specified.

    lol haven't read... the 590 are no more in this rig they are now in my HTPC.
    anyway there wasn't too much bottleneck as 9550 were at 4.2ghz and nf 790 ultra overclocked too and i were in DDR3.

    there is not much at all with the 1366 950.

    i should really update my profile :pc1:

    I would wait for IB-E at the end of 13
    you can either get a 4930 or drop your 3930 in it and save money
    same socket
