Not bad, but I don't fully agree with sata drives especially the one you got.

Here you go, pick this one up instead, I have 2 of these in my computers.
Pumping hard for almost 4 years now, haven't had one bad sector yet.
If your looking for a quick drive for media/videos office work and some gaming get it.
You'll have more space to you in case you record any videos or use it for backup data purposes.
I talked to a old friend of mine, if you use this on 7 it will boot up between 10-20 seconds.
If you use 8 and keep the drive properly fragmented and check for errors on a normal basis...
Boot up time on my windows 8 based computer is about 5-8 seconds flat straight from the bios posting. :/
Also I don't agree with your psu, its a good one but check your setup.

You got a godzilla of a machine especially with that video card and other components.
Yes its a 119.00 so what, if you look into the drive I picked out you can afford both if you want to.
