Gigabyte Z370 ATX motherboard?

I don't know why but I tend to buy Gigabyte after a series of broken MSI motherboards. Anyone know if Gigabyte has an ATX z370 in the works? I need lots of high speed slots - 8x raid, 8x network card and a 16x video card and I like the option of throwing in a second video card.

Thanks for the quick reply and the links! I was hoping to find one with 4 16x slots which gives me a little more flexibility where I place things and so if I get a 2nd video card I can team them.

Oh and I should have mentioned, I want 2 onboard nics and a creative sound integrated as well. I couldn't find one with everything unless I get an old system with the old chipset like my current motherboard. (GA-170x-G1)

You're not going to find a 4-slot x16 mobo, for Z170/Z270/Z370, without using a PLX chip. And someone bought that company, and apparently, they are now too expensive to use on mobos, at least the ones that you'll find under $400. At which point, you might as well go with the X299 platform and Skylake-X, if you really need that many PCI-E lanes. The mainstream CPU/chipset, only supports 16 CPU PCI-E 3.0 lanes, and 24 chipset lanes, which are funneled down to 4 lanes, where it meets the CPU and memory controller.

TL;DR - You're buying the wrong platform. Think bigger.

SLI or Crossfire is all but dead. It seems a lot more work (and costs more) than it's worth dealing with incompatibility and driver issues. Better to just buy the top single card (1080ti), and call it a day.

Plus, your Z170 board is not what I would call an "old chipset". It might not have 6 cores like the new Coffee Lake CPUs do, but the Sky Lake and Kaby Lake CPUs will hold their own for several more years, unless you are a bench-marker. Plus, it looks like the z370 chipset will be a one-off platform, with the possibility of it being a very short-lived socket once the z390 hits towards the end of next year.

Or the OP could go with the X399chipset and Threadripper instead. Which gives 64 PCIe lanes.

Thanks - I never really understand the 24 lanes or more with PLX. I believe my current system has the PLX. It seems to handle full throughput with all my components fine. I do need a second PC soon and want it to have all the features of my current rig but I'm not sure I should seek out an older motherboard and CPU.

Stop right there, Z370 won't be nearly enough PCIe lanes for you. It's either X299 Skylake-X or X399 Threadripper that you want if you really need 32+ lanes. Or go full workstation/server platform.

Because of product segmentation, the best bang for the buck would be to get a Threadripper 1900X + X399 board for 64 PCIe lanes. You'd have to step up to the i9-7900X ($999) on the Intel side to get 44 lanes.

OK - I seem to be able to get full bandwidth utilization of my video, nic and raid card when I do benchmarking using my current set up which I believe is a 24 lane cpu but with a plx on the motherboard. Not sure if the PLX is giving me the throughput I need or I just don't need as many lanes.

Thanks everyone for your feedback. I'm guessing my best option is to work around my backup and try and hold out about 8 months for the z390 and hope they come out sooner along with a CPU with 40 lanes.

I seem to get good performance in my current situation perhaps due to the PLX chip on my motherboard. Anyone know of any new motherboards for the z370 with PLX?

I hear you...
I've done the switch few years ago to asrock, pretty good so far.
