Could you get one motherboard with 4 PCIe 3.0 slots and have two NVidia Dual-GPU cards and two AMD Dual-GPU cards and choose between quad-sli and quad-crossfire depending on what game you wanted to play?
Of course this is completely impractical but if you had an unlimited budget could someone do this? Would the drivers conflict?
