ASRock has done a fine job bringing all of the newest features to the 890GX Extreme3 motherboards. This board has SATA 6 Gb/second, USB 3.0 and even external SATA 6 Gb/second. The UCC chip allows users to unlock locked cores assuming the CPU can do it. The other feature that really sets this motherboard apart from other 890GX boards is the three PCI Express x16 slots, allowing three ATI cards to be set up in CrossfireX mode. Overall, with good performance throughout, the 890GX Extreme3 is a good example of the 890GX platform and ASRock has a very decent board on their hands.
