Summary: I put this on an old AM2+ board with DDR2 memory and it runs amazingly fast. Feels 2 times faster than the Athlon 64 X2 2.2GHz I replaced. It also runs very cool and pretty quietly with a Cooler Master Hyper TX3, also thanks to its low 95 watt TDP.
I am very satisfied with my AMD Phenom II's performance, it's like a new PC

Summary: I bought this AMD Phenom II X4 945 to bring an old but still functioning Asus mb up to 2013. Since this is the most powerful cpu this mb will accept after the BIOS update I feel this cpu is the best to deal with today's Debian programs,it has a pretty low thermal footprint(95w)perfect for this pc runs 24/7, no dislikes. The only other products I compared were lower speed Phenom II X4s. I've built quite a few pcs, all with AMD cpus and never been disappointed.
