Same here. -Skipped SB because my Phenom II felt fast enough at the time. The plan was to upgrade when IB came out. -Skipped IB because it wasn't any faster than SB and overclocked worse -Finally going to upgrade when Haswell comes out. The difference between IB and Haswell is small, but the cumulative improvement when you skip several generations adds up. I guess that's the idea with Intel's tick-tock scheme... +10% with SB over Nehalem, +10% with IB, + another 10% with Haswell. In the past, we had clock speed bumps, then more cores and IPC improvements. I think that era is over. Clock speeds have stagnated at 3.5 - 4 GHz. Core count has stagnated at 4-6 "real" cores. IPC improvements are limited to ~10%. This has been pretty obvious since around 2005 or so.
