Pros: To start it worked the first time. I bought it 12/18/2012 with the F15 version of the Bios but still ver 1.0. However even with 1.0 it was fine; I still upgraded to 1.1. I do NOT have Windows 8 so I don't know if there are any issues for Win 8 users. The BIOS is cool and it works fine. It's more flash than substance but nothing to knock off or add on and I'd imagine for the less savvy it probably would add to it more. Overall it gets 4 strong eggs. There is one con however...

Cons: Overclocking past 4.0 GHz can't be done. The bios starts to restart itself if I do it. I have a 3570k i5 processor. It should be able to do it. I tried using EasyTune 6 first (it's a Gigabyte program that allows Overclock settings to be done through the OS; you set it, restart, and it should apply the settings) however this didn't work. I then tried doing it manually. I did 3.8 (the 3570's advertised rate for overclock) and was fine. I tried pushing to 4.0 and the BIOS didn't like it. I'm pretty sure it's the mobo as the same processor can go over 4.0 GHz on my brother's computer. He has the same processor but uses an MSI mobo. Works fine for him and other than that our computers (built same day) are effectively the same other than the Mobos. I've tried getting in contact with Gigabyte..and that's just not happening. Maybe it's the holidays but with only 30 days to return I'm starting to get cranky.

Overall Review: The one egg off is half for the OC aberration and half for the fact that I can't seem to find a way to fix it either through my own means or through Gigabyte. That irks me.

Pros: None

Cons: Put it in and the fan would stop working sometimes other times would speed up immediately and die again. Tried my old video card and no problem. Tried my brother's Gigabyte 670 and it worked fine. This card was just not working; it didn't run cool and it didn't run quiet.

Overall Review: Just drop 50 bucks more for the Gigabyte 670
