[SOLVED] deciding between B450 or X470 motherboard for use with Ryzen 7 2700

[bbeennyy1000]

hi!
im finaly upgrading from an archaic AMD FX 8350 to a ryzen 7 2700. i spent all my money on the cpu and ram and need a board. i was originaly going to get the lower end MSI x470 board but black friday ended and they are back up in price and im not sure if i should bother selling things and or loaning money from friends and family to pay for a fancier board. i plan on overclocking the 2700 to 4 ghz and running 16 gigs of 2666mhz ddr4 with a 1070 an m.2 and a pcie soundcard.
ive tried overclocking my 8350 on cheap 970 boards before and have had them overheat which is why i want to be careful in my board choice this time.
so the question is will a b450 board be good enough to overclock above 4ghz at reasonable temps? to they have good enough vrms for that? and will a cheap (sub 180cad) x470 board give me better enough results to fork over the extra 50 bucks? also do x470 boards have features that would benefit me or be noticeably better over a b450 in general that would be worth the extra dough?(more pcie lanes, faster ram support, better vrms, more m,2 slots,pcie 3.0 x4 speeds for m.2, etc)
also im probably going to keep this cpu for another 5 years like i did the 8350 so id like to be as reliable as possible and my case takes regular atx.
sorry about the novel ive typed but i like to be specific!

thanks!

stuff going on the board will be a ryzen 7 2700, 16 gigs of ddr4 2666, an m.2 ssd, GTX1070, some sorta soundcard in the future.

You're going to find very little actual differences between the x470 chip set and the B450 chip set. Both allow the overclocking you're interested in, and both will support the other configuration options. Also, what you'll find on most x470 boards is, most use the exact same VRM section as the B450 counterpart motherboard of the same design, until you get into the top tier for the brand of board you've picked. So, you're not going to get a better VRM, just because you went with x470, until you take that jump from the $100 - $150 range boards to the over $200 boards, and that sounds like it's going to be out of your budget anyway.

The biggest difference between B450 and x470 becomes whether you want the PCIe bifurcation for things like multi-gpu support and a few more USB 3.1 Gen 1 ports, both of which probably won't be major issues 2 years down the road for you. It will always be better to get a faster single card than to try going multi-gpu just to find that the titles you use the graphics cards for either don't support the tech or don't support it well, or your PSU is underrated for both cards running full tilt.

Not sure what your ambitions are for adding a sound card. It may actually be completely unnecessary depending on your usage.

If you're using audio out over HDMI, the sound is generated by the graphics card, so sound card will be useless. If you're otherwise going to use digital out, the on-board sound should be more than adequate as the signal bypasses any of the on-board conversion circuitry, and some built-in codecs support Dolby Live encoding for gaming surround using coaxial or optical with 5.1 speakers. Sound cards really aren't good for much anymore unless you are specifically using their analog out or some sort of headphone amp feature, however if you're that picky about quality audio feeding into a headset, I would look for a proper external headphone amp for that purpose.

Also, if you use something like Bluetooth headsets or USB headsets, those are their own audio device and would also end up bypassing any installed sound card.
