Pros: Cools my Athlon 64 X2 6400+ nicely - I had seen hear that many of the reviews on the 6400 stated the oem cooling solution was insufficient so I opted to try these instead - Installed easily enough - Runs quietly - Idle temp runs about 95-F and under a gaming load 115-F.

Cons: None yet

Overall Review: Installed this cooler as part of my 2 other X2 6400 upgrade projects (mothers and wifes computers) - No problem with any of them - Also recommended to several friends who purchased these from NewEgg as well.

Pros: 6 Sata3 (SATA 6Gb/s) and 4 USB3 ports all seem to have no problem with backward compatibility. Dropped it in added the CPU and 8 GB (G.SKILL Ripjaws Series 8GB (2 x 4GB)) of ram and it posted on the first try.

Cons: The side mounted SATA ports are a pain with my case as they are next to impossible to access without pulling my drive carriage out which is easy enough, but a hassle. The over-sized heatsink was almost too close for a standard AM3 cooler (ZALMAN CNPS9700 LED) to fit clamp on. It fits, but it is very close

Overall Review: Dropped a AMD Phenom II X6 1090T into this and we were off to the races. I did update the bios before I installed Windows 7 onto a G.Skill SSD and I had no problems at all. This is my third Gigabyte board and have been happy with all three.

Pros: This baby rocks - drop in an Athlon 64 X2 5200, add a couple gig of corsair DDR2-800 ram (TWIN2X2048-6400C4) and your off to the races. Was concerned about memory compatibility / configuration issues, but encountered none.

Cons: None worth mentioning.

Overall Review: Most expensive board I have bought, but seems to be worth the money
