There is an amd board with 2 ddr2 and 2 ddr3 slots that will take am2 or am3 cpus. The asrock n68c-s UCC is ideal for someone in your situation. You can change later to am3 and ddr3 with this board. Don't expect to overclock or use 2 video cards with it. It's a low budget board for doing regular stuff on your pc, not for enthusiasists. And when you upgrade, read the "cpu support" section on asrock's website before changing cpus.
