2x7990 or 4x7970
#2
You better have 4x7970. 7990 is not an official card, it take huge amount of power and take 3 slots. (Tests showed that it slower than 2 separate card as the 7990 is basically just 2 7970 crossfired)
Lot of motherboards support 4 Vga, if they have enough PCI-E slots. (AMD driver is limited to 8 GPU per Motherboard)
