I have prebuilt Acer Aspire M1100 CPU.
AMD Athlon 64 X2 4400+
F690vgm Mobo (here's more info on it)

Ati Radeon HD4850
500W PSU
4GB DDR2
Any more information you need just ask.
I have budget of 150$ to get a new mobo if necessary but definitely a new processor. I have no clue where to start. Any help would be awesome.
