The only thing i would change is the 6870 for a 7850, it is about 15 euros more then the 6870 and the performance in certain games is quite big. Here take a look at the fps results of the two cards, see if it is worth the extra 15 euros: http://www.anandtech.com/bench/Product/549?vs=540
Other then that, it is a solid system. Should do fairly well in games and it is a good build.
