Yes, it is underwhelming and many people's expectations were very high, but it is not as bad as many people claim. For one, the "OMG I MIGHT NEED A NEW PSU" is just retardedly blown out of proportion. Not that efficiency is good, but it is absurd to think that you would need a new PSU for this chip, especially if you already have a hexacore, unless you are pushing the thing to the ABSOLUTE limit and any little bit more will kill it.
That said, PLEASE stop posting GPU bottlenecked gaming benchmarks as an indication of this or any CPUs performance, IT JUST DOESNT WORK THAT WAY. I dont care if its a "real world" situation, if it has a GPU bottleneck the CPU is not stressed 100% and therefore not indicative of its performance. If you want to see how this chip will perform in the "real world," go look up a benchmark for the GPU you plan on using, as that will be the limiting factor most of the time and dictate the FPS you get as long as you CPU can surpass it, and any halfway decent CPU will, including this one.
You don't compare the performance of two cars going the speed limit.
