Only one graphics card can be inserted in B85-HD3-A, and two can be inserted in B85-HD3. PCI e x4 has one more. Audio B85-HD3 has three more jacks than B85-HD3-A ... The hard disk capacity on the motherboard is also more than that on the A motherboard.

On the power supply, B85-HD3 has one more phase than a motherboard, which is suitable for I5 E3.

If you are I3, I suggest you choose B85-HD3-A. ..

Everything else is good. The main reason is that hardware manufacturers like to locate their products separately in the same model, and there are many styles.

The electrical components are not bad, and Gigabyte is suitable for the middle and low end. The advertising language is super durable and has a good reputation.
