I can see that i7 860 is much better than the i7 920 but most of the forumers here prefer i7 920 more than i7 860...I want to know why...
If you check some of the posts here in LYN and other places, you'll see that the i7 920 clocks very well due to it not being tied to an on-die PCIe controller, so the LGA1366 platform will probably outperform the best LGA1156 in the hands of a good overclocker. That's what I gather la, so far.
But then, as 1156 matures, coupled with the faster access times of dual channel DDR3, applications that matter most to consumers may favor the 1156 more than 1366.
There are a few sites that tested the i7 920 for games, and the conclusion is that unless you're running GTX260 SLI or above, the bottleneck is at the GPUs. It takes tri-SLI and CrossFireX to really stretch those Nehalems.
On apps that don't have hyperthreading code, you may even find that the i5 750 is about as fast as the higher end procs due to similar clock speeds and only 2 or 4 cores utilised.
So unless you do a whole lot of photoshopping or video rendering/encoding, the i7 860 or i5 750 would be more than enough for most ppl. Don't forget also that 1156 uses less power than 1366
