Well I have been toying around with a single 1070 to see if I could use it as a place holder over my 480's while waiting for Vega to drop and I can decide if I want to go that route over the 1080Ti.
So let us start off with the issues I have had with the 480's.
Original system specs
5820K@4.54
4x4GB DDR3200
Gigabyte X99M (x2)
Customer water loop
Corsair Air 240
Antec TPQ1000
With that setup I had nothing, but issues even with the cards stock, swapped to a Seasonic 750w Platinum and had no improvement, my assumption the PCI-e bus hunger of the 480 was too much for the GB board which was actually overheating the chipset/VRM sections when the cards were run in crossfire (it was fine with xfire off). This also hit right around the time I got a 6850K which when tried with the GB board didn't help anything, but OC'd just as well as the 5820K. Killawatt meter shows 600-650w MAX at the wall
System redux part 1
6850K@4.54
4x8GB DDR2400
Asus X99m-WS
Custom loop
Corsair Air 240
Seasonic Snow Silent 750w
With the new Asus board swapped in I still had issues with the cards. If left at stock they would play for an hour or so and then shut off. Top card was running very, very hot (90C+). So I attributed issues to the heat. I found a clearanced/EOL Case Labs Mercury S5 and rebuilt the system in that with the intent of going to Vega or 1080Ti's anyway.
With the new case I was actually able to run games without issues at stock settings (power limit/clocks for the 480's). The S5 allows me to use the bottom most PCI-e slot with a dual slot card giving an air gap between both cards. Temps have now stabilized to a max around 85C with stock fan curve and stock settings.
Weirdly enough I am still having shut down issues with any kind of overclock. Board temps are fine, CPU temps fine, GPU temps fine. System still only shows 600-650w max at the wall under load. For shits and giggles I order a 1200w Seasonic Prime, using the logic that if I ever want two Vega cards or two 1080Ti's I will need the extra juice with everything overclocked anyway.
Guess what magic happened? Boom no more shut downs. Cards run loudly, but stable at 1430/2100
+30mV +50% TDP. They can hold those clocks through most games with minor fluctuations due to the top card eventually getting hot.
Only thing I can assume is the cards were peaking and tripping OCP on the PSU. Well since that frustrated me I happened across a 1070 and decided to see if it would be worth it to dump the 480's and just deal with the 1070 while I wait.
For those of you making the argument that the 1070 is a better buy etc etc. Please make sure the person using it is not playing on a 4K monitor. The 480's now that they are working correctly often pull the difference between playable and not playable off. The 1070 really struggles with GTA5 at 4K. Dips into the 30's consistently vs the 480's holding a consistent 80-100FPS. I thought something might have been broken on the 1070 after this, but benchmarks match perfectly to what a reference card should do. Doom was a similar story, fallout was a game when the story swapped to the 1070 for the most part performing better. Overall just a really big wash for me. Luckily most games I play support xfire making this for me a tough decision to dump the 480's when they offered soooo much better performance in most of my games.
Oh well there is my food for thought. Maybe I will dump the 480's and grab another one of these el-cheapo 1070's for a bit. Also don't talk shit about my cables it is just tossed in waiting for the "to be cards"
