It's just a start. I'm waiting on my other 3850 at the moment and my Phenom 9850. I'll start with a 5000+ BE and tri-fire. Using a PCPower&Cooling 750 Quad, and two sticks of Transcend Jetram DDR2 800. After testing with the 2 3870's + 2 3850's, the 3850's will be replaced with two single slot 3870's. More to come. Some testing to be done next weekend.
