Building a Gaming PC, help please!

Hello! Looking for some advice on my gaming PC building project since I'm a beginner and this is my first time building one.

  • Budget. around 1500€ (1900$), can be exeeded for a reason
  • Where do you live,  and what currency do you use? Finland, Euros
  • Do you need or already have peripherals? I already have a monitor, kick ass keyboard and mouse.
  • What will you be using your future computer for? Gaming, Rendering (Mix of both) and it is basically my TV aswell.
  • Do you overclock or want to get into overclocking? I am a huge noob when it comes to this but if it is simple enough I'd love to give it a go aswell!
  • Do you plan on going for custom watercooling now, or in the future? No plans there.. should I?
  • OS. Do you need a new one? I think i will run Win7??

If you Game-

  • What kind of settings do you like or what FPS do you want to play at? What should I go for with this budget?
  • What resolution would you like to play at? What should I go for with this budget?
  • What kind of games do you like to play? Dayz, CS:GO, WoW, Fifa, etc.

If you Render or Edit things-

  • What application do you use to render? I edit render some gaming footage to Youtube with Sony Vegas 12PRO, but I can change if needed?
  • Do you render movies or just photoshop pictures: both

Other Notes:

  • What is your general experience in building computers? Is this your first build or are you seasoned and just looking for advice? 1st timer, looking for some solid advice

This is a set I had in mind: (it is from a german site since it is sooooo much cheaper, (and nope, I don't speak german eighter)

 what do you think? pros? cons? How about clocking / overclocking? how to improve? Should I swap something? 

Thanks in advance!

You probably have to screenshot the cart - the link won't work for us.

Have a look at this ... Is it close to what you are thinking?

Used an overkill PSU so you can add a second GPU in the future. 
Sony Vegas will work well with the R9290x and the i7 4790k CPU with 16GB ram

and I could not find win 7 64bit on the partpicker so just added a 64bit Win 8
