Tomorrow, my Dad and I are going to look at a new Gaming PC for me, and we saw this for sale:

Windows 7 Ultimate
AMD 3.6ghz quad core CPU (3.9ghz turbo)
8GB DDR3 1600mhz RAM
500GB SATA III 6Gb/s HDD
HD 7560D Graphics
USB 3.0
HDMI
HD audio (6 channel)
DVD player/writer
It's only for $400, it that a good deal?
