  1. i7-920.
  2. by alot or not really
  3. Best answer

    what do u mean by that
  7. I mean the i7 is ahead in heavily threaded apps while the i5 will be better in others.

    i7-920 vs i5-2500k

    It's better than the i5-2500K in most applications, so this means it will be better than the i5-2500.
  9. what about for gaming
  10. I5-2500K is being held as the best Gaming CPU por the last months, so yes i5-2500K is better, worth the upgrade ? I'm not that sure.

    Few games use more than 2 or 3 threads. The extra hyperthreads of a i7-920 will be largely unused.
    Also, the 2500 is more efficient than the 920, by about 15% clock for clock, and the clock rate is higher.
    If you get the "K", you can also get an easy OC to help things more.

    If you already have a sandy bridge 2500k, there is no value in upgrading to a ivy bridge 3570K. But for a new build, I would go with some sort of an ivy bridge cpu. They are even more efficient per clock than ivy bridge.
