What is it with people wanting AM3+ with crappy graphics all of a sudden?
Anyway, what is the use case for this PC? You will need a graphics card to get decent performance with games, which would, in turn send you down the 900 series chipset path. AMD does not officially support AM3+ CPU's on anything other than an AMD 900 series chipset, moreover, the power gating feature of the FX CPU's is turned off on anything but a 900 chipset. If this isn't being used for gaming, have you considered an APU-based system? It comes with a far better GPU and, although the current architecture is Phenom II, it is still powerful enough for most activities. Trinity will be the next APU but with a Bulldozer x86 core and a Radeon 7000 GPU.
