When you look at the cost of the TR motherboards the small difference in CPU prices becomes a very minor issue. Not that is competing with that Intel CPU anyway as this is aimed at a much much smaller niche.
YES! (y) I wholeheartedly agree.
I'm not sure why you keep quoting me as saying things I never did, my comment was in reference to this quote: "Who would actually need an 8 core TR im not sure? who would use one for fun or in a soho? Although at this price who cares!" As in, it's not an impulse purchase at this price and most other people will or should just go for a mid-high end quad-core which will do most of what they'll need perfectly well. Also, I wouldn't lump content creators (a real job) in with YouTube streamers (a pseudo pretend role for the entitled generation)!
The 16 cores are going to be the sweet spot for a while even when the 32 core threadripper is introduced later this year. You really have to need the features of these chipsets though to justify it, because for most anyone else they are much better sticking to the consumer AM4 socket.
Threadripper is not a average user product, It is extreme user platform specially for YouTube streamer or content creators who will go for Intel i7 8700K which is atm more expensive than this can hugely benefit from the multi-core count and additional memory slots and PCIE lanes. And i believe whoever is looking at this thread and serious about buying it knows that. Myself just couple of weeks ago built the Ryzen 2700x system and won't go for threadripper as I don't have need for that.
