I put together a system with this board a little over two years ago and it's hands-down the most reliable system I've ever had. Although I realize it's getting to be a bit on the obsolete side, I've yet to find a system that games much better, even with the older DDR. There's a reason the board is still $180+ despite the fact that 939/940s are on the verge of extinction - matter of fact, we're putting one together right now for my bro-in-law. SLi a couple of 8800s and you're flying high!
