OCC has published a review on the ECS A785GM-AD3 Motherboard

Unfortunately, there is not much here for high-end gamers, as CrossFire is not supported by the A785GM-AD3 and graphics cards with large dual slot coolers will block the top two SATA ports, leaving only the three bottom ports available. Let's face it though - this board is not a high-end model and if issues like these bother you, I am sure you are willing to shell out the extra cash necessary to avoid them. In the end, the ECS A785GM-AD3 did exactly what is supposed to do. It was stable, performed well and had many great features due to the 785G/SB710 chipset combination.
