Have you ever known someone that just has to tinker with things? You know the guy I am talking about. It is never good enough. There is always one more tweak, hack, or adjustment to be done to get that few extra MHz out of their systems. Well, imagine a room full of the same people. This is what you get when you talk about ASUS’ R&D team. ASUS makes some great boards, but to the R&D team it is still not enough.This team of tinkerers continues to improve on their designs with new BIOS features, new drivers and in some cases, new revisions of products that ASUS already has on the market. It is this mindset that allows ASUS to produce the excellent products that they have. Today we are taking a look at one of these; the ASUS M4A89TD PRO/USB3. This is an AMD 890FX based motherboard that headlines the upper end of their mainstream products.As the name suggests, the M4A89TD PRO/USB3 does have USB 3.0 on-board along with a host of other features. These features include Turbo Unlocker, Core Unlocker, Turbo Key II, TurboV EVO; all for only $184.99 on NewEgg.com. Will the performance of this board along with the features list equal the price? You know what to do to find out.
