if you want a fairer comparison, the i7 920 is about as good as a i3 2100 except in muilt-threaded tasks where its a fair bit betterhttp://www.anandtech.com/bench/Product/289?vs=47
you can always overclock your i7 to gain more performance
Got no interest in OC as I said my system runs games just fine now and is plenty fast still. The post was more about with the games and engines on the horizon, will this system last until mid 2015 when skylake is going to hit.
Gotta admit, it is depressing to see my I7 on par with and in some cases out performed by an I3 even if its a generation newer.
