I emailed AMD about Graphics cards number limits they haven't replied yet after about 7days.What I've asked is:..

[wtfnow]

How many cards together do they support in one pc (I've read on a forum that there is a driver limit of 8)
Why is there a 4 card limit in crossfire
If I have a 8 slot board how do I crossfire all cards?Double crossfring? (2 times 4 = 8)Or what?

Any guesses on these questions and why arent they replying??

 

[wtfnow]

come on any ideas??

What are you trying to do? If you want to add them up for more performance in gaming, realistic maximum is two GPU's, technical limit is 4.
