[Build Help] Critique build for my girlfriend.

Basically, a cheaper CPU/mobo combo that will still be great, a video card with 3GB of RAM (if you want), a cheaper but still good PSU, and an SSD to improve loading times. The SSD will give you a much more noticeable performance increase than the CPU will.
