You could use a CPU upgrade. Gigabyte says that motherboard will support a Core 2 Duo or Quad, which would be tons better than what you've got now. Also, it can support up to 4 gb of RAM, so if you could find a couple of 2 gb sticks that are compatible that would help as well. What are you planning to use it for? If you want to play games or do anything graphically intensive, you'll need a better video card too.
