I'm 100% against the Mouse and Keyboard. They're both pretty bad. Mad Catz is notorious for making crap, their mouse is no exception. The twin philips laser is horrible. The logitech keyboard is all show.
Mouse: Steelseries - Full performance, modest eye candy (only full featured sensei) or Something like Corsair or Logitech
Keyboard: Just aim for mechanical key switches. Cherry MX Red is nice for gaming. I use Browns and hate Blacks.
CPU: Eh... AMD... eh... I don't know what to say. I have the highest end AMD CPU at work and they're not as good as I expected... To switch to intel you need a new mobo, and that's extra money you have to spend.
GPU: Nvidia 660Ti or AMD 7870 should suffice.
