Well this is my pc.
What mobo should I use? I was set on m4a77t/usb3 but then I decided to use the most incredible tool google and I saw some nice reviews on M4A89TD. The price difference is about 2x but I can affoard it. So... Which 1 is better and why ? (Also please explain the usb3 price value)
Welcome, Newcomer. For starters, you're looking at two different NB chipsets.
the M4A89TD is only better because it comes with SATA 6 Gb/s, while the m4a77t comes with only 3Gb/s. So, if you want to pay 2x more for 2x more SATA speed, then it is a worthy expense.
In a nutshell, USB 3.0 promises the following:
Higher transfer rates (up to 4.8 Gbps)
Increased maximum bus power and increased device current draw to better accommodate power-hungry devices
New power management features
Full-duplex data transfers and support for new transfer types
New connectors and cables for higher speed data transfer...although they are backwards compatible with USB 2.0 devices and computers
