I currently have this pc:

I have been using it for gaming, recording, and running small servers. At some points I have been getting some lag issues. My plan is to hopefully upgrade to an intel cpu and a new motherboard. I am thinking about the i5 3570k and maybe an asus motherboard. I am wondering if anyone has suggestions or any other input?
