I got an 1100T because I started out with a Lenovo H405 pre-built rig, which had an AM3 socket. So I figured the cheapest, most effective upgrade was an 1100T, until I bought it and found out the motherboard wouldn't support a 125w TDP. Then I bought a new mobo, which wouldn't support the custom Lenovo front panel connectors. Then I had to buy a new case, and before you know it I have a custom setup lol. So I have an AM3+ socket now, but I already bought the 1100T, plus I've read that the FX series was kind of a disappointment and in ways inferior to the Phenom II X6 series.
