Getting a new mouse will give you about another 15FPS in games all depending on brand and so fourth...But seriously no real advantage or disadvantage just if you want a new mouse get one that is comfortable has all the buttons and stuff you want. but do you really need one? I would say no, and BBrotherwood is right about cable price. I was bored an was walking around PC-World-Currys and found them selling a scart lead for 15POUNDS! FOR A SCART CABLE!
