Coolermaster PSUs can be a bit hit-or-miss, you would be best to go with a better brbrand such as Corsair, XFX, Seasonic, EVGA, SuperFlower, Antec.etc.
As far as AMD, if you are gaming you are still better of with Intel regardless of the number of cores. While the AMD CPU has 8 cores, they are significantly slower than on an Intel chip. Most tasks such as gaming benefit much more from fewer, faster cores over lots of slower cores.
AMD is fine for the video card though, just bear in mind that AMD's video cards don't work that great with Linux.
Also,.definitely get an SSD, both Crucial or Samsung make great SSDs.
