recent tests in MANY magazines and websites demonstrate that the i5-2500K outperformed all but the most expensive i7s in everything but highly multi-threaded apps.
My last post showed that the extra performance also comes at a cheaper (MUCH cheaper for comparable performance) price than the i7s too.
The ONLY proviso in all this is whether or not you intend to run heavily multi-threaded apps. In this case, as you say, the top-end i7s will be better, but even then many people would be put off by the extra expense.

Now - can someone answer this?:
gtx560ti 2GB OR gtx570 1280MB ???
for CoD obviously,  , at 1680x1050 or 1920x1080 and for high settings. |
"many magazines" doesnt really count as a source...
That being said you havent read the post - the i7 can be clocked to more or less the same OC clock as the i5 can, they are both the same price (930/920 cheaper and 940/950 slightly more) but they have double the threads. Now its getting really tiresome, but do you seriously think the thread count of apps wont be increasing rapidly from now on? New phones coming out are dual core, the new ipad 5 is probably a dual too. BFBC2 runs 8 threads. Now even if you only run 4 threads, so even with the i5 - the clock is the same, the i5 SB wins slightly interms of speed because of the new mem/arch BUT the i7 can run the OS and other apps using the spare threads and comes out even or on top. In addition this gap will only increase into the future.
I5 SB will always lose to a i7 N unless its a K version SB then you can OC it, then its even until you get to newer software and the I7 wins. Its the better longterm buy.
