does the b85m hd3 support another 4-6 display if I add my old gpu hd 5450 with 3 output? I m not familiar with latest mobo bios and I m not sure if this board allow igfx and dgpu coexist but it seems it only give me 3 options in bios>peripherals>Initial Display> as iGFX/PCIe/PCI. i dont see any iGPU or multi monitor enable/disable like some Gigabyte user i read in some forum. I need at least 4 Display for productivity work. tnx
