Monitors 1 & 2 go into either DVI ports (the ones on the top), HDMI (I assume you know what those look like) ports or 1 of each and the 3rd monitor goes into a displayport port, which are the smaller ones across the bottom in the case of this card
No, you can only crossfire/SLI 4 GPUs since a 7990 already has 2 you can only have a maximum of 2 of them in Crossfire
1. Now I don't see what you mean. I think the other guy explained it better, are all 4 at the bottom Displayport Ports, and both at the top DVI ports? If so, where are the HDMI ports?
So the third monitor goes into a displayport port, got it. Now where exactly do I put 1 & 2? I don't comprehend this very well.
