Pros: Fast as hell, Windows regcognized with no problem, both chips. Pretty fair price. Overclocks like a dream on my K-9-n M-S-I board

Cons: Beware and be patient when clipping the heatsink to your motherboard/CPU. The locking arm is very hard to snap over after you clip the hooks to the reciever on the board.

Overall Review: runs 3d studio max renders and can surf the web at the same time with no problem. I'm not really a gamer or anything like that, but if you're a video editor and/or 3d artist this is the chip for you

Pros: Overclocking interface is awesome, built in CPU temp monitor. Tech support was great for me, people were helpful and got me running when I had any problems

Cons: Heatsink is right between the PCI express ports. Havent had a problem yet but kind of a wierd design to be dispersing heat near your VGA's

Overall Review: M-S-I's tech support is great. I'm not sure why poeple are ragging on it at all. Their website has a huge forum for any problem you could think of for any product they make. Tons of updated drivers for the K9N on there. Sure theirs bugs, but AM2 is new technology and is bound to be buggy. Check their website for test builds if you plan on buying this board. It will help you to not have any compatability issues folks. research research research...
