Not sure if this has been posted here yet (search didn't show much) but another Chinese website has dropped an entire Haswell review. http://www.xbitlabs.com/news/cpu/di...edged_Intel_Core_i7_4770K_Haswell_Review.html Looks to be pretty much on par with Ivy, only with better IGP. Now I guess the only reason someone with Ivy would have to upgrade would be IF Intel decided to use a soldered IHS. At that point, for someone with money to spend and who truly cares about such things, it may be worth migrating. However, it seems like it may not be a worthwhile upgrade for performance.
