I'm currently running an Acer x1200 slimline pc with an Acer model WMCP78N motherboard. It's based off of the nVidia nForce 720a chipset, and sports an AM2+ socket. I currently have a 65w Athlon X2 4400+ inside of it, and was looking to upgrade to the AM3 Phenom II X3 720e, another 65w processor. I've read that the AM2+ socket was designed to accept AM3 chips, but I haven't seen any documentation on if the Phenom IIs work.
Before I order this chip, I was wondering if anyone knows if it will work or not. Also I am going to be looking for an AM2 replacement that is just as good, using the same wattage.
