I've read somewhere that this motherboard can hold up to 5 GPUs: http://[Suspicious link removed]/NXTZC4

However, as I asked my reseller if this was true, he replied that it can hold 2 graphic cards on PCI-Express 16x slots in crossfire mode.

Can someone explain me what does it means? This is the same article on the reseller page: http://[Suspicious link removed]/NBjadK, it really looks like the same product to me.

Do I really need crossfire mode? Can I connect 5 GPU do that motherboard, install windows and start mining at full power?

EDIT: since I can't post links, here's the name of the motherboard.



and here's a photo:
