Cpu question

[Kreekakon]

And an another question to line, is there better graphics card than this Asus hd7850-dc2-2gd5
for the ~300€ price?

I don't think so. That graphics card is already peaking the top of extremity. If you get your hands on something like that, chances are you won't be needing to do a tech switch for another three or four years lol
