No that is not necessary, only for SLI/spitfire. You can put two graphics cards in one pc without that and they will both work, just not together.

Kevin is correct.  You can have different make and models of video cards on the same machine.  I have an Nvidia ad AMD card running at the moment.

I have one Nvidia card mining Dogecoin and it is overclocked with interactive mode disabled so it is being used as much as possible with no negative effect on my usage.  Then for my main card which drives my dual monitors, I am using an AMD video card which is not mining.

@Scott, Do you happen to have instructions/tutorials of how to set this up?

<p>I have a GTX660 right now, but I bought an R9 290x recently. I was wondering if I can leave both in my pc and use one (the GTX660) for Bitcoin mining and one (the R9 290x) for everything else (mostly games).  </p>

<li>Will it decrease gaming performance to run a miner on a separate card?  </li>

i7 3820 @ 3.60 GHz<br>
16GB DDR3 RAM @ 1333MHz<br>
Asus 2011 P9X79 Pro<br>
Windows 8 pro  </p>

<p>I bought the new card for gaming, but if it would be possible to do this with my old card without losing performance that would be great.</p>

Surely you want to mine something other than bitcoins? Also [check this out](http://bitcoin.stackexchange.com/questions/9854/why-do-amds-gpus-mine-faster-than-nvidias) concerning your choice of the GTX for mining.

# Can I use one graphics card for games and one for Bitcoin mining, without losing performance?

(Asked by: username_0 on 2014-02-20)

I have a GTX660 right now, but I bought an R9 290x recently. I was wondering if I can leave both in my pc and use one (the GTX660) for Bitcoin mining and one (the R9 290x) for everything else (mostly games).

1. Is this even possible?
2. Will it decrease gaming performance to run a miner on a separate card?

The rest of my specs:  
i7 3820 @ 3.60 GHz  
16GB DDR3 RAM @ 1333MHz  
Asus 2011 P9X79 Pro  
Windows 8 pro

I bought the new card for gaming, but if it would be possible to do this with my old card without losing performance that would be great.
