Naturally the Thubans are the buzz of this post and rightfully so. I have a high end 965BE rig so I decided to "improve rig 2". I used an Asus M4A77td couple with a 720BE "cooled" by a Zalman 9700. Threw 4 gigs of ddr3 at it with Win 7 Home Premium 64 and WHAMO! Used ACC feature to enable all 4 cores to run and clocked it at 3200 (16x200). Have been running Prime 64 over 2hrs with temps at 46C max. The mb controls the cpu voltage between 1.39-1.42. So far so good.
Fun to get so much performance from a $99(at newegg) chip!
