well the 860 is a better processor than the 920 but the 920 runs on a better platform. The 860 is a 1156 cpu which means it runs on dual channel memory and only has 16 lanes of pci express bandwidth (meaning in sli or crossfire each gpu would run on 8 lanes) however it has better turbo boost and runs cooler than the 920 and it is also faster than the 920 at stock frequency and still benefits from hyperthreading. The 920 on the other hand while not a better processor does run on a better platform, you get triple channel memory, two pci express slots both at 16 lanes (on an x58 mobo) and in some cases the abilty to have both crossfire and sli on the same board. before i continue please pay no attention to those who say "the 1366 is more future proof it's as if people never learn,you can never be truly future proof since technology changes all the time and also both sockets were launched at the same time to cater to different markets that does not mean that the 1156 is not going to be developed at the same pace, there is no evidence that supports the theory that somehow the 1366 is a more futureproof platform, sure the gulftown six core cpu is going to come out on the 1366 first but no one can say that it is not eventually going to be made for the 1156 socket as well....it is just the tendency for some people to always want the latest and greatest regardless of whether they need it or not the same people "waiting" to buy hexacores will be the same people who will jump ship the minute they hear about octacores or dodecacores coming out...these people worry more about bragging rights than anything and ought to be ignored....in the end it comes down to the type of usage for gaming you will be fine either way multi gpu solutions will be better in the 1366 however the real world difference between the two platform is negligible, if gaming and mainstream use is the main purpose then the 860 is the way to go, since the cpu runs cooler and the platform cost is cheaper allowing you to save money for what really matters, the gpu (even dual gpu set ups don't take serious performance hit) if heavy multi tasking and video encoding or other cpu intensive tasks are your main concern then the 920 is better since the triple channel ram and better chipset will also provide better mutli tasking abilty.
