My old motherboard is broken down and I'll buy a new one but I don't know which chipset is the best one for my processor?
Does my processor supports DDR3 ram?
Its not even worth getting a motherboard for that CPU your best bet would be to atleast upgrade to an AMD Athlon II.
You could reuse the DDR2 RAM you got and get a cheap AM2+ motherboard and an Atlon II which will run circles around your P4 for about $150. It is really not worth putting money into that old of a system.
^+100. Ditch the P4 and get a cheap AM2/AM2+ board (assuming you have DDR2 RAM, if not, get an AM3 board with DDR3) + AM3 CPU (make sure the board supports AM3 CPUs).
