I have been building a rig. My mobo supports 4 x 16x GPUs and I have enough PCIe power from the PSU. But, how many 7950s can Be crossfired max? 2,3 or 4?

4 can be in CrossFire.  The scaling sucks but what can you do.   Cheesy

I assume you want to use them for mining, then you don't need to xfire any of them, it will not earn you any better performance
