Bit of a strange Question, I currently have an R9 270x toxic, which is fine for gaming, but i use blender and can only render with my CPU at the moment, i was wondering if it was possible to put an Nvidia card in under my r9 270x and just use that for rendering, but use the AMD card for everything else.
I am willing to Upgrade the Motherboard, and PSU if necessary.
any recommendations would be welcome

my current system specs are this:

CPU: FX-6300
Motherboard:GA-970A-D3
RAM: Kingston HyperX red (2x4gb)
GPU: Sapphire R9 270x Toxic Ed
CPU Cooler: H100i
PSU: Corsair CX500w
Case: Carbide 300R Windowed

Did you read that link in the video's description? They're running two AMD cards in crossfire and two Nvidia cards in SLI - these two together in the 4 slots of that motherboard.. Also they're much expertised in doing tests like that.. They'll also might have failed several times before making this combo work or they've something specially used.. you can see in the youtube comments that some saying "Nvidia and AMD should make a card together, allow interconnecting with either of their cards and the video poster replying back that'll never happen, etc etc..
No, the AMD cards and Nvidia cards will never work together.. Also, your system will use the both GPU always (say when you have two AMD cards in crossfire or Nvidias in SLI) unless one is disabled.. make a AMD crossfire by adding another R9 270x to your current build or try upgrading to a new better GPU..

You may be able to detect both and switch between them. I'm not sure if it will work, but in theory each card should be able to process outout for different monitor. It won't work as sli/crossfire when 2 or more cards process signal for one monitor. Each card will need it's own monitor or you will need one monitor and some kind of switch. Also I would not try to run them under load at same time as who knows what it would do to your CPU.

In worst you should be able to run them in way that you will be constantlly enabling/disabling cards.
Before I had laptop with integrated amd graphic and dedicated amd graphic. And I was able to set it way that laptop screen run on dedicated and external monitor on integrated graphic so it may work same way.

But warning it's just theory, if you are willing you can test it and tell us your results :).

If you watch video they did what i suggested. Just plug them in with 2 monitors or 1 monitor with switch and after that just switch display or gpu on software base.
So just switch main display from one running on AMD to one running on NVIDIA and it should work.
There is no reason for it not to work. For OS its just another piece of metal plugged in. As they warned in video for example nvidia control panel dont like to run at same time as amd or something like that so you will need to learn to respect that and know when to open/close which panel or switch graphics, but technically there is no reason for it not to work.

Those 2 cards will NEVER process same image at same time but you should be able to run 2 displays with 2 different cards at same time and in worst your CPU may bottleneck you if you try to run them under load at same time. Ofc be careful to have PSU powerful enough to run both.

If you want to use just ONE at time just switch main display as is described in video and it's ok.
