What games are you playing? None of those choices are good for modern games. A few points to consider:
1. Whenever possible, buy the Phenom II's or the FX line of CPU's over an Athlon. The Athlon's are meant for lower-end systems without many demands. Even if an Athlon II X4 was clocked at the same speed of a Phenom II X4, the Phenom II would win due to a more efficient architecture.
2. Buy at least an AMD 800 series motherboard, if possible, a 900 as these are newer can take newer hardware. Be aware that most current motherboards take DDR3, not DDR2 so you will not be able to reuse your RAM. You will also have to reinstall Windows from scratch.
3. If you are using the same HP case, you will probably have to use a micro ATX board as that is what the Pavilion used for the original now-fried motherboard.
