Hi,
I currently own a Sapphire HD7970 Vapor-X 3Gb GHz Edition. I've been thinking of adding one more GPU and Crossfire them. However, I am a compete noob when it comes to Crossfire.
The card currently available in store is Sapphire R9 280X Toxic 3Gb. My question:
1. I've seen people saying 7970 + 280 works, but is this combination a complete waste of money?
2. Which card should I make as primary?
3. Both cards are OC-ed at the factory. When they XFire, will any problem occur?
4. When crossfire, the system will take the card with lowest clock rate. In this case, will it make the 280X a complete waste of potential?
Thanks a lot and hope you guys can help out. There's a lot for me to learn.
