Summary: I got a Core i5 3330 for free so I just needed the surrounding peripherals to go with it - Motherboard, Memory, and Heat Sink. ~$270 later I had all three. I decided to spend the extra $30 for this motherboard over the cheaper 1333 FSB Intel board and am glad I did - the system is actually faster...
Summary: I had no issues with it out of the box. I popped in 32gb of RAM and it fired right up. I chose it because of some of the legacy connectors on the back plane. In the past couple of years, I've been around from Intel to Gigabyte boards and Intel boards for me are always plug and go---never any issues.
Summary: The heatsinks on these chipsets are spring loaded, they need to twist the heatsink as it is locked down and this could be causing the thermal compound to smear away from the metal die on the chip. Hopefully if anyone else has this problem this fixes it for them as well.
Pros: Worked great for 3 years, then the USB controller started to fail intermittently. Overall I would buy Intel again.
Cons: USB started to fail intermittently after 3 years whenever the temperature in the room reached about 70 F, I found the thermal compound under the chipset heatsink was not applied properly so I bought a tube & gave it some fresh compound. So far the fault has not come back.
