Why is that an issue with Asus cards?
Also, where can I find the "Nividia's guidelines for max voltage and boost clock" ?

Hmmm, so you're knowledgeable about OCing with various tools, but you've not read or heard about the common buzz on the net regarding the many complaints of Nvidia voltage locking these 600 series cards?
The typical max boost voltage most 670s ship with is 1.175 volts. It's pretty much Nvidia's standard max recommended voltage. Any card vendor that chooses to go over that does not quality for the Nvidia GPU warranty and chooses to put their own warranty on it, MSI for instance with their "Triple Overvoltage" cards.
The max boost clock can vary depending on the model of 670 you get, but it correlates with how much voltage you use. The main thing Nvidia really pays attention to is what voltage is used, because any boost clock you get will be limited by that, and voltage is the main thing that can cause damage if you use too much.
Then there's boost percentage. By default the max boost percentage is like 10% over the default built-in boost. Some cards can achieve much higher than that. This all wasn't really even an issue until Nvidia implemented auto boosting than can't be turned off, and voltage locks that come with warnings of no warranty if they're broken. This is why card vendors that unlock voltage boosting have to use their own vs Nvidia's warranty on the GPU itself.
On the wide frame rate fluctuation, I've only read about it recently in perusing Hardwarecanuck's roundup review on some 660 Ti cards, which uses the same GK104 chip. I combined that with TPUs reviews of the 660 Ti cards showing the MSI 660 Ti PE OC beating the ASUS 660 Ti TOP at much lower clocks with max OCs on both. I'm not saying it happens with all 600 series ASUS cards, and either is a good choice, but it was an eye opener for me. That's why I said
IF you get any problems with wide frame rate window. It's not necessarily a given.
