And for people in Europe, do you know possible places where I could find prices lower than this (not too far from Beligum for transport fee)?
Rue Montgallet in Paris (
http://www.rue-montgallet.com/ ). Your motherboard and your proc are each roughly 40€ cheaper there (I didn't check the rest of your stuff). I basically assembled all of my PCs with parts from that place
As for the brand for the GPU you'll be better off with a good brand (like MSI, BFG, or eVGA) as they will offer a more reliable product with often greater performance. They tend to be more expensive though
