One slight problem, is that your chosen websites don't seem to want to translate well, into English, and appear to be very limited in options. I have, therefore, put something together, using German sites, so components should be available, it's just a question of WHERE.
As you have a slightly limited budget, it is probably best to forget the expense of i5 processor, and concentrate on powerful graphics, using an Ivybridge i3 processor, which is plenty for your needs. In order to allow you to add a 2nd graphics card, I have suggested a Z77 motherboard, which, itself, is suitable for doing overclocking. You could, therefore, use an i5-3570K processor, and aftermarket cooler, to give overclocking, but that would exceed your budget.
CPU: Either i3-3220, or i3-3225 (the 3220 is cheaper, but may not be available)
Mobo: Either ASRock Z77-Extreme 4, or ASRock Z75 Pro 3 (the extreme 4 is better, especially if you want 2nd GPU, the Pro 3 is cheaper, and adequate)
Memory: Corsair Vengeance CML 8GB(2x4GB) 1600 MHz C9 DDR3 (or GSKill Ares similar)
HDD: Seagate Barracuda 500GB 7200rpm (obviously you can judge if size suitable). Western Digital Caviar Black is "better", if it will fit budget.
GPU: Gigabyte Radeon HD7850 (slightly overkill for your monitor, but would be best, in case you upgrade monitor. HD7770 would be OK)
PSU: XFX Pro Series 450w, or similar 450-500w from Corsair, Seasonic, Antec, or BeQuiet. There seem to be limited good choices, in Europe.
Opt Drive: Any LG, Pioneer, Lite-On
Case: Mid Tower ATX
For power supply, optical drive, and case, it's more a case of what is available. The best way, is if you find a couple of each that "seem" suitable, if you can refer them back here, we can tell you if one is "better" than another.
Depending on you choices, that should give a well performing system, in, or close, to your budget range.
