Nope. If your run 2 grafics card in SLI /Crossfire they act like 1 grafic card and mirror the vram. But thats not what you need. You can mix all different kinds of grafics card in your computer as long as they work on different task / games.
You can have 4 games run on your current GPU and others on the second GPU.
Ths is not true. In SLI the cards have to match or SLI won't work. Crossfire will only work with compatible cards. You can run different cards to different monitors but unless you specify which monitor it displays on, the program will default to the primary adapter.
They claim with Windows 10 and DX12 that you'll be able to mix and match Nvidia GPUs with AMD. However, nobody has tried yet.
