Hey guys,

I came by this pretty powerful GPU. However it has no output and it wont show anything on screen. However if I want to use it as second card, can I use its power? By power I mean her 4GB power for games for example. I want too use them both on single monitor. However I’m more interested in her KH/S power for mining bitcoins or dogecoins for example.  
Tanks for all answers, as you see I’m not really experienced, sorry for my English! [http://m.bestofmedia.com/sfp/images/design/usr/smilies/smile.gif](http://m.bestofmedia.com/sfp/images/design/usr/smilies/smile.gif)

Are you not a bit late to the bitcoint party 😛 maybe your card is listed here? [Mining hardware comparison - Bitcoin Wiki](https://en.bitcoin.it/wiki/Mining_hardware_comparison)

Yes you can - however I have slight problems with reading the sensor data for the “unused” graphic card if the “connected” card is from different chip vendor (nVidia/ATI). But you will be able to mine with the card - just make sure the card is well cooled.
