You have to compare similar Mobo's. The CH6 is the go-to mobo in the Ryzen world
It is? Unless you need an insane amount of external USB ports, it really isn't. The Taichi will get you about the same level of performance and features for $50 less with better VRM configuration, and that's if you go X370. If you are running a single GPU setup or if you plan on sticking to Crossfire only, you can actually get about 95% of the same features out of a B350 board. Plus if you ask chew*, he'll tell you that it's easier to OC RAM on B350 for some bizarre reason . . .
In fact, I would like to know what wonderful features I get out of the C6H that I can't get from the ASRock B350 Pro4. Here's what I can tell so far:
- a third PCI-e slot which is virtually impossible to use with a video card that has a dual-slot cooler.
- some RGB lighting yay
- Crossfire support
- USB 3.1
- some fluff for "xtreme OC"/watercooling crowd which you would probably not use with a 1700 anyway
- a CMOS clear button
- bclk OC, good luck with that if you use NVMe
- the onboard audio might be better. Maybe?
Comparing it to my Taichi (which has built-in wireless, something the C6H technically does not have; you must buy an extra module for that), the only things I would really miss are the built-in wireless and the CMOS clear button. Though I do love me some low VRM temps. Ask Mark, he's got a Pro4. It'll get you to DDR4-3200 and has for awhile. Just pop in a 1700, clock it up to about 3.9 GHz or so, and let er rip. It just works.
This problem comes up whenever we discuss HEDT vs. mainstream/"client" platforms. You can't just compare a $250+ x299 mobo to an AM4 (or Z270) mobo in the same price range and expect that anyone buying a client-level board actually looks seriously at the $250 board. HEDT is all about high minimum cost-of-entry. There are PLENTY of x299 users out there who would jump at a $199 board (or less) if they knew the OEM would give them the power delivery they would need for the chip. It just so happens that a lot of client-level users can get away with weaker VRM setups. You don't absolutely need a 12-16 phase board for a 7700k, unless you are really going to push that thing, and even then, maybe not. It looks like you really need it for x299.
And on x299 they will make sure you pay for that stuff.
Maybe you are the type of person that refuses to pay less than $250 for a board; if so, Intel's HEDT and AMD's upcoming x399 ought to be right up your alley. For everyone else, platform cost becomes a real issue. You can have a positive user experience with a motherboard that costs $100 or (slightly) less.
Even an entry level X299 board typically has higher quality audio, power delivery, etc. than your run of the mill low cost B350/X370/H270/Z270 board.
At least in the case of the power delivery, you really don't need it for AM4 or LGA1151, do you? As far as the audio goes . . . okay? Great.
