Im looking for a new AMD motherboard to go with 6870 crossfire and FX 8120 CPU I'm currently using M5A88-V EVO the problem is the overclocking on this board is bad ever time i set the CPU Voltage to manual the screen stays black and it say overclocking failed and the pci express 2.0 x16 x4 mode im getting bad crossfire performance low gpu usage on most games sometimes i get more FPS running on 1 card
PC Power and Cooling Silencer Mk II 750W
x-fi titanium pci express x1
I look at the specs for your M5A88-V, the problem with your crossfire is the slots are pcie 2 x16 and x4; the board isn't really a crossfire board, when ever you see only two pcie 2 slots and there different colors than it means the board was meant to have one card not two. This could be causing issue with the OC issue as well since the north bridge is 880 and the south is a sb850. I giving you three options just incase you would rather stay with asus or stay closer to the same price point.
