Can I plug in radeon 7950 in a PCI slot?How might it affect mining performance?

You cannot plug in a PCI-E card into a PCI slot. It is physically impossible.

However if you do have a free PCI-E slot - Radeon GPU's are great at mining. It all depends on your motherboard and power supply though.

Don't expect to get rich off it...
 


maybe some cable converter or soma like dat?

 


not for mining
