Maybe NVIDIA will go back to 3-Way and 4-Way Graphics Cards in their Next Generation.
Then I would think about a new computer.
there is NO SLi no more or crossfire
Developers use mGPU from now on - so you can have as many cards as you want now and intermix them
so anything new(Game wise) does not have SLi settings
DX12 uses mGPU
why do you want to stay on DX11 and an OS with no support - both from software side(OS and no updates) and driver support on Hardware side?
nevermind that New hardware may not work in Windows 8.1,7 or older and older hardware not not work on 10(not certified or supported)
