I kinda want a Ryzen. I just bought a 2700K to replace my 2500 - more for the K rather than the i5 > i7 boost - but more and more things are multicore, and I want to get an up to date system; M.2 SATA, USB 3.1 and the like, and the prices they're talking about are *really* bloomin' tempting.
I could never justify upgrading to a new Intel system, but this is really tickling my pickle

Thanked for using "tickling my pickle" as a descriptor. Damn I love Hexus.
On a more relevant note, is it just me or do Asus boards feel a bit boring and generic? Lots of people trust them, they have all the required features, reliable, etc etc., but even their ROG just seems boring to me - all grey, black, red, no interesting designs. Just sharp edges to hurt yourself on. I'm sure people like an understated board with the right colours too, but for Asus' brand I would expect one interesting pick like the Taichi.

So far Biostar are the only company who've announced an mATX X370 board AFAIK, and their implementation doesn't support multi GPU (the second physical x16 slot is 2.0 x4, and is shared with one of the other PCIe slots so can drop to x1 depending on how many cards you have plugged in). Hardly surprising tbh - most enthusiasts will go for full ATX, and unless you're intending to support multiGPU in an mATX board there's no compelling reason (that we know of so far, anyway!) to use X370 over B350 in mATX boards - B350 provides plenty of peripheral connection possibilities and supports overclocking.
EDIT:
Just spotted this in the ebuyer listing for the ASUS Prime X370 Pro:
Think that's the first "official" confirmation of ECC support for Ryzen processors! (note, he same listing also confirms that Bristol Ridge APUs don't support ECC).AMD Ryzen™ Processors
4 x DIMM, max. 64GB, DDR4 2666/2400/2133 MHz, ECC and non-ECC, un-buffered memory

Not seen a single ITX board on any of the sales sites so far either.
Ebuyer have a few boards up, Scan have the best selection though many without price against them. Novatech you have to search for "AM4" as they don't have a section to browse yet but they do have product.
Edit: Novatech have a pre-order price for the 1800X which is £100 more than everyone else!
Another edit: Looks like Novatech are now undercutting everyone else by a quid, guess that compensates a bit for their postage costs.

So if you use SLI or Crossfire the PCIE 3.0 slots run at 8x electrically rather than 16x.
Seems a bit poor, is that more of a CPU limitation with the number of PCIE lanes available?
Except it's been demonstrated repeatedly that the drop from x16/x16 to x8/x8 is pretty negligible in 2 GPU setups...
Yes - the CPU only runs 16 PCIe 3 lanes, so they have to split them x8/x8 for multi-GPU. Bristol Ridge APUs only have 8 PCIe lanes to start with, and won't (AFAIK, anyway) support crossfire even in an X370 board.
But to be fair to AMD, this is exactly what you get from Intel's consumer platform as well. It's tempting to compare the entire platform to X99 because AMD are offering 6 and 8 core chips, but it's worth remembering that AM4 is a consumer platform first and foremost. I'm pretty sure there will be server/workstation platforms for Zen-based Opteron chips that offer more PCIe lanes. For consumer platforms, I think AMD's right, and there's no real benefit in providing extra PCIe lanes for multi-GPU when x8/x8 will do the job just fine.
I have to admit I did wonder if any mobo manufacturers would hang PCIe MUX chips off the CPU provided lanes to enable "full" x16/x16, but presumably they decided that it wasn't worth the extra cost...
If your spending the money on going for a dual GPU setup you are obviously after the best performance possible so the potential *slight* drop in performance would matter to them (well would matter to me).
I'm not much of a fan of the way Intel are doing things at the mo (prices for chips, not much generation to generation improvement etc.) but they catered for the enthusiast by offering chips with different number of PCIe lanes (if you were willing to pay). Still feels like AMD isn't trying to win that top percent back. (Yes a know in numbers terms it's a small segment of the market but it tends to have the highest profit margin, plus Halo affect)
I had thought that some mobos might have an additional chip to provide extra PCIe lanes (like some do on Intel boards) but haven't seen any yet.
It's on the official page too:
https://www.asus.com/uk/Motherboards/PRIME-X370-PRO/
And ASRock list it for some too:
http://www.asrock.com/mb/compare.asp...g,AB350%20Pro4
And one of those is B350 not X370 unlike with Asus and it looks like this AB350 is one their cheaper board:

Well, Ryzen 3 and 5 aren't even out yet, Naples is probably still in final development, maybe give AMD and the board partners a month or two to sort out a niche product environment for you? AMD hardly has the resources Intel does and this product launch hasn't really begun yet. We're effectively seeing their version of 7700K here, nothing more. Plus, if you wait longer the BIOS revisions and reliability, plus chip OC headroom, should come. Rome wasn't built in a day.
But only the top end chips have 40 lanes, and you have to pair it with a high end motherboard that splits it into 16x/16x instead of allocating it to other things like M2 slots, USB3.1, or more SATA connectors. When scaryjim says it's negligible he really means it - it doesn't have an effect on framerate pretty much at all. Hell if I remember right even at 4K there was no drop in performance, but don't quote me on that. I think it was Anandtech who did the tests a wee bit back.
You'd be really shooting yourself in the foot if you forked over extra money on the CPU/mobo purely to get 16x/16x
