So, hello guys!
I bought a brand new 1070 (MSI Armor OC)
and accidentally they shipped a second one aswell... anyway I talked with them and they say because I had a lot of problems they give me that card for free.
Now I have two 1070's laying around and I thought of SLI... and my PC and everything is SLI capable so I did.

Everything works fine but is there any thing to have in mind when using SLI?
For example I got an old Oculus DK 2 here, can I use it?
Can I put one monitor on the one GPU and one onb the other?(I got 2 Monitors)

Thanks guys,
Noah

Hey there. This is a late reply but seeing as nobody has answered your question, I will let you know what I think...
The main purpose of SLI is to use multiple GPUs to increase game performance.

There are a couple of ways to use multiple graphics cards. You can go to the nVidia control panel and configure SLI settings.

- Maximising 3D performance: works with all the monitors plugged into the top graphics card, and will use any graphics cards to try and make the games run faster. This will require an SLI bridge (usually supplied with your motherboard), but note that a lot of games don't support SLI and you will have to do some fiddling to get SLI to work at all. I personally find this fun, but it can be tedious and there can be some...

- Span displays: I think this works with monitors plugged into any of the graphics cards, and will allow you to tile the displays together into a large screen. I am not sure about this, I haven't read up on it and I have very little experience with this.

- Disable SLI: Each graphics card works separately. This means you can plug any monitors into any graphics cards. All the rendering should be done on the GPU that is displaying the screen, but games and software will usually be run all using the primary (top) graphics card and therefore you might not get any performance benefits.


For Oculus stuff - At the moment, I don't think there is any VR support for SLI. I have not read up on this recently, but I doubt this will have changed. But don't worry! You do not have to turn off SLI if you plan to do VR.

Im hoping this was useful! Its a wall of text and I suspect you already know the majority of this :)
