Ignoring the silicon lottery means you could get anything. If it's a golden chip you might see 4.8Ghz. 
I've actually got the z87 version of that mobo myself and it works fine. I can OC to 4.3Ghz, but I think that is mostly my CPU not being good at overclocking. The heatsinks on the board are fine for well over 110w, but that's the highest I've ever gotten my 4670k. The only limitation I've seen on the board is that the CPU vcore is limited to 1.3v, at least on mine.

I would only go as high as 4.4-4.5ghz at most. The board is lower end and may not be able to push much past the stock clocks. The chip itself will run fine up to 3.9ghz, as that is the chips normal boost speed anyway and any board that supports that chip will support that speed. On stock voltage you should be able to get 4.2ghz easily.
If you would like to get around 4.6/4.7ghz, then start looking at the Asus z97-a, or the MSI gaming 5 as a good starting point.

According to this list the PC mate has only 3 true phases with a doubler making it a 6 phase board not 8, and I would not recommend overclocking to the maximum on that board for 24/7 use: http://cdn.overclock.net/0/07/071b2d45_1.png
4.4-4.5ghz is what I recommend at most for 24/7 use with that board. Sure it can go higher, but in reviews they only test for a few hours or a couple days at that clock speed. Not for months on end, or maybe even years like the end user may want to do. Getting past that mark requires too much voltage for long term use IMO.

Yeah that board is 6 phase(3 true phases using doubler to get 6) not 8 and yes maybe you should leave the forum if half of what you do is insult others. We are just people trying to help.
Oh and on your advice of maybe hitting 4.7(or higher) with that board is pretty stupid if you ask me. You have to put so much voltage on chips to maintain those clock speeds that you risk shortening the life of the CPU/Motherboard greatly. It is generally recommended to not go above 1.3v with the devils canyon chips on air, and getting to 4.7/4.8 requires a fair amount over that to stay stable. http://www.anandtech.com/show/8227/devils-canyon-review-intel-core-i7-4790k-and-i5-4690k/2
Then there is the heat generated by having the voltage that high. The CPU can get really close to throttling, which introduces another issue. So who is giving bad advice here?

Let's all try to agree to disagree and remain civil. No need for insults or the thread will be closed. A lively debate with disagreement is always welcome, but let's not insult. And please do not reply to this post as it is OT and will close the thread. Thanks to all and carry on.

Honestly it is recommended to NOT try extreme overclocking on budget boards for 24/7 use, especially on air. They are budget for a reason, and there would be no point to buy higher end boards for overclocking if they were just as good. They are constructed out of lower quality components overall usually. I refuse to recommend to someone that they should try to hit past 4.5ghz on a budget board like this. I wouldn't want to be the cause of someone destroying their computer because of bad advice. If someone buys a board that is manufactured with high end overclocking in mind, and they have adequate cooling to do so, I have no problem with it. I'd even try to lend a hand, lol.
Recommending a lower end board for high end overclocking to me would be no different than recommending a Coolermaster PSU over a Seasonic PSU, and expecting the same quality. It just wouldn't make sense, and could be incredibly stupid, not to mention dangerous, lol.
PS: If you haven't noticed, I have a i5 4690k and I have a much higher end board than the PC Mate. Even with this board I have to set 1.35v for 4.8ghz, 1.325v for 4,7ghz, and then I drop to 1.27v for 4.6ghz. That final drop keeps my temps at 70c max, and the other settings hit between 80-85c. That is in the winter as well in Canada. I personally wouldn't want my chip running over 80c, 24/7 365 days a year, and that is why I dropped back to 4.6ghz and let it be. The chip is not a bottleneck either way, and would very much like to keep this computer for a few years so I am playing it a little safe for now. If I grab a water cooler, then I might try going higher again.

I would argue that, if you're trying extreme-ish OCing on budget boards, air is a better idea. You'll cool the VRMs more (which is especially important on budget boards), and chip temperature will limit you before the board becomes an issue.

I got to ask you though. How safe is it to do, and how much risk do you think would be involved for a machine running 24/7 at over 80c for a couple years? Would you personally recommend it?
EDIT: I guess I should of said for roughly 4 hours a day 24/7 365 days a year, lol. Sorry.
