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

Where does that speed add up to? Reading / writing into the harddrive? Does gaming experience benefit at all from this?

I'm assuming you're referring to the USB 3, as 6Gb/s compared to 3Gb/s is pretty simple to understand.

The speed of USB 2.0 is a mere 320 Mbps. So barring physical limitations, basically anything connected to the USB 3 port can be affected by the speed increase.

Gaming would not benefit from USB 3.0. Besides your hard drive that stores the game files, games rely on CPU, RAM, and GPU; none of which interface with USB.
