Can I mix and match GPUs for mining

[srepen]

Hi I have a current gaming pc which has one 7950 card, it gives around 500 mh/s

I am hoping to get another card to increase my mining hash power, do I have to use another 7950 or can I get 7970 to work in the system.

Pretty sure as long as they are 79xx you should be ok, but I would wait for someone else to respond first before you buy anything else

Yes, cgminer allows you to use different settings for different GPUs, just be careful that you know which is which

cgminer -n will list all GPUs in the system

cgminer -i 10,20 --gpu-powertune 0,20 --scrypt

will run GPU #0 at intensity 10, powertune 0, using scrypt
and run GPU #1 at intensity 20, powertune 20, using scrypt.

i typically run seperate instances of cgminer by using cgminer -d 0 and cgminer -d 1
