The Gigabyte duo are a remarkable pair - One for the enthusiasts and one for the value market, yet both give just about the same level of performance. If you are interested in the budget style or for the extra features, you have no worries about choosing Gigabytes boards.
On the 8IEXP side, the overclocking would have been a bit better if you could raise the CPU core voltage up to 1.85v instead of limiting it at 1.725v. This is really the only problem we had with this board. Every peripheral needed for today's computing, including Firewire was included. Performance and stability were beyond what we had expected from Gigabyte.

In all, we rate this board 8 out of 10.
