Pros: It seems efficient and usually stays around low power usage for my gaming machine.

Cons: Giving this only 2 stars and I'd consider that generous because it's just not starting up every time. It will turn on for a couple seconds then just decide to turn itself off. This has been extremely annoying and is corrupting my bios. I have to go through restore process every time the power supply fails to kick in.

Pros: Its durable. I guess. I see nothing wrong with the hardware.

Cons: The drivers on this thing are killing me. I've run into 2 major issues that have wasted almost my entire last few days, it's honestly making me really regret buying this. First after installing Windows 7 Pro, I ran into a problem right away. Popping in the driver cd that came with this. I installed all drivers and everything seemed fine. Restart computer. Bluescreen on login. Some service that I just installed was starting up and instantly bluescreening the computer. This service seemed to be slightly delayed in safe mode to a few seconds after login. Anyway I decided to just install the ethernet driver and get the other drivers online. The second problem is even worse. I updated first and one of the windows updates contained a creative labs audio driver. This driver worked as far as I could tell, but there was no control panel with it, and so I could not switch the microphone on to the front jack. I then proceeded to uninstall it and install the creative driver from the gigabyte web page. Everything installed fine and I rebooted. Now my sound was completely gone. It was clearly detecting the microphone and headset now and going into volume control I could see the little green volume bars jump up and down on the device as I played any sound. But nothing came out. I've tried reinstalling the drivers several times. Removing everything possible from the system in the process. I tried to get all registry keys related to Creative using Guru3D. Anyway, nothing works and this has been giving me a massive headache. Uninstalling the drivers now also does not bring sound back. I have to install the gigabyte's creative driver and then click "Rollback Drvier". Then sometimes (about half the time), it will bring my audio back. But then I cannot configure microphone to front jack again because there is no driver. This is just a disaster and too much hassle to deal with. I really don't want to reinstall windows completely again to "maybe" fix my problem, but I guess I will have to try. Anyway, this brings my review down to 3 eggs. Another egg I am taking off for the audio being bad quality in general. Not the actual sound but the faint static in both the rear and front jacks. I guess I shouldn't have expected much from onboard audio, but the product claimed to have good audio so I thought it would be different this time. Nope. The last egg I am taking off for the BIOS. Immediately after installing and trying to configure things in the BIOS i noticed that it randomly becomes extremely slow and sometimes freezes after I click around. I noticed no pattern in the things I clicked. It just fails and this was really really annoying as well as I'd have to restart and redo all my bios modifications (as fast as I can before some kind of freeze spell magically kicked in).
