Rough Estimate: 1000 Euros without monitor, OS, Keyboard, Mouse etc
Since you don't plan to overclock I went with the locked processor which is about 30 Euros cheaper than the k versions (unlocked for overclocking)
If you don't plan to overclock you can get by with the stock cooler but the cooler master 212 evo would be a bit quieter if you want one of those. I didn't use pcpartpicker for this since the availability on the website you provided is more limited.
Also, SLI/Crossfire is putting 2 of the same GPU into a system for increased performance but requires more power and generates more heat (so needs better cooling). The performance increase is not double but closer to 1.3-1.5x what the single card could do. I typically prefer a single card solution since single cards have better driver support, generate less heat, I dont have to buy a 750w PSU, and are more stable all around.
