    Am I now better off with it off?
    Would OC'ing maybe be a little more stabile?
    Maybe even temps?

    Thank you for any replies.

    Why not just Try It (TM) with HT off? It's not like you will be doing any permanent damage..

    Off for networking on for gamming..................That sums it up.

    Best of Luck...

    There aren't that many programs that will actualy run slower due to HyperThreading. It brings a certain comfort, comparable to multi-cpu systems, especialy if you like switching between many tasks.

    You can turn it off if you're using Windows 2000 though.

    they're aren't that many programs that use hyperthreading are there?

    Any multi-threaded application is capable of getting a performance increase due to HyperThreading & running two single-threaded applications at the same time is much smoother.

    I did just that. ht (on/off) made small difference in temps:
    off: -4°c
    on: +5°c
    Programs load faster with ht off and slower with ht on but only the first
    time progarms are loaded. Must have something to do with L2 cache.
    With ht on it splits the cache 50/50 between the 2 virtual CPU's.
    When I'm running a lot in the back ground a switching between them, my temps
    with ht on actually go down. With ht off running same load it slows a bit and temps go up.
    All this done OC'd @ 3.4.
    I dont think there are any multithreaded games and not that many enduser programs.
    I hope they get it together and put the $$ and time in to it with
    the on set of the true dual cores and quads cores.

    My system does quite well for me, however Sean summed it up, I am topped out with older technology.
