There are also up to 7 OC bins for unlocked processor models. Just like Sandy and Ivy Bridge models support right now. Again. The only limiting factor is the UEFI where someone can say STOP and write a 0 in a certain MSR and then NO GO. Then they let you pay extra for a so called OC board and surprise surprise. Now the restriction is lifted. The pre-selections menu might even be gone, but now you are in full control. This enabled the motherboard manufacturers to make a little extra money. Nobody will admit it, of course, but that's the way things are.
And to give you an idea: Here I have a menu with 100 MHz (the default), 125 MHz and 167 MHz to select from, and below that there is a -/+ sign plus input field where I can change the pre-selected value (5~7% up/down).
Also. What people here seem to be missing is the hugely improved memory OC ability with support for up to almost 3 GHz. For me and my G.Skill 2800 MHz DDR3 modules, this is where most of the gain comes from. DDR3 OC heaven!
What? I don't know where you get your info from, but what you're saying is misleading/wrong regarding BCLK.
BCLK is fully adjustable. That was the case on SB, and will be the case on Haswell. The problem is that when you adjust it too far outside of 100 mhz, PCI-E, SATA, USB, etc. devices are dropped due to them not having tolerance outside that range.

If you can wait, 4770k. If you don't want to wait, 3770k. Simple as that. 4770k will at least be equal to the 3770k, but if you have software that can take advantage of AVX2, it will be up to twice as fast as the 3770k.
