Is this PC any good? [PC BUILD]

Hi. So, Windows 8 was just released and I’ve decided to build a brand new PC to experience it on. (Note, this isn't about Windows 8, so please do not post something like: "Windows 8 is crap with mouse and keyboard" because I've been using the Release Preview for quite some time already on my old ThinkPad T60 and it’s really good. Thanks)

What will I use it for?

I'm building a PC that I'll be using for:

  • Casual stuff. Web surfing, writing documents, visiting this site :)
  • Photoshop, InDesign, Illustrator for graphic design work
  • Watch 1080p movies on my TV through HDMI
  • Stream my movie collection to my phone (and hopefully, one day, tablet)
  • Light gaming. Right now the only games that I want to play are Skyrim and Diablo III. I've already got a PS3 and a 360 as my main gaming machines.
