Pretty sure Claymore's ETH miner supports simultaneous mining with cards of different architecture (mixed mining). Or you can just launch two instances of the miner with different config files.
Not sure if you can mine with both graphics cards at the same time, since you have two different card from two different manufacturer.
It does. My most stable rig consists of four 1060's, a 470, and a 480, all running in a single instance of Claymore on Windows 10.Pretty sure Claymore's ETH miner supports simultaneous mining with cards of different architecture (mixed mining).

1000W+ power supplies are probably the biggest hit after GPUs. You can find some under $200, but all the quality units from brands like Seasonic are overpriced or out of stock.
So, I've got a pair of 850's myself, and can confirm if you've got multiple cards stacked off risers, none will actually power on until the riser powers on.I found that too, once you get into the 1000w range the prices go up fast. I ended up going with 2x 850w psus as it's actually cheaper than a single 1200w psu and gives more overall power.
I'll probably rig the secondary PSU so a relay turns it on and the relay will just be powered by the 12v output of the first one. The relay will just control the power on wire so just any old relay will work.

My primary rig has 5x 1080ti's, PSU1 gets mobo,
If you want to relay/combo switch them, it works too, I've got a little plastic $5 jobber that I was going to use until it apparently became unnecessary.
ex: one psu's 12v rail might be 12.1 while the other might be 12.3, will that actually cause some weird 0.2 voltage difference/loop that could blow components?
Yeah, that's what I was trying to clarify for @Red Squirrel, that he can have two PSUs in a rig without actually daisy chaining/linking them. PSU2 can just stay turned on. And yeah, same, I tried to keep the load low, I've got two of those 850 Seasonic PRIME platinum's, they're stupendous. Got two more for my actual gaming rigs.Actually, that happens because PSU1 is the one that powers the motherboard. The secondary PSU can sometimes be on, but the system itself isn't on until the main PSU is. I had a setup of CX430 main + Quark 650W secondary powering 3 cards, so speaking from experience. Perhaps that's what you meant by "riser" though. Riser in my case means PCIe risers.
Has anyone figured out why the 1080 has so much lower hashrate than the 1070, and 1070ti?
My 1070ti is easily cranking 30Mh/s while my overclocked 1080 is hanging in around 23Mh/s. Kindof irritating.
What I do wonder is what happens when all the BTC coins are mined.
Not that it really matters. I think its at 16 million out of 21 right now, and the projections are that it'll take something like year 2145 to get all 21 million. It'll take longer for Bitcoin to get to 21 million than it took for vast majority of the modern technological advancements.
Assuming you are in your 30s, its hard to say even your great grandchildren will be alive by that time. Renders it all moot, because plenty of things can happen in less than 5 years, nevermind 130.
Oh wow did not figure it was going to take that long. I guess with the difficulty increasing it does exponentially go slower to mine.
The only way I see bitcoin staying relevant in the future is if people will adopt it as digital gold replacement, it doesn't have any other utility.
