Thank you Emperus for your suggestions it's really appreciated! Unfortunately I'm buying it in a store and they got sort of deals for their "selected pieces" and I cannot get other brands than the selected ones. But for the graphic card I think I can get a hand on the one you proposed since my actual Pc come from the same store and they sell Asus. By the way whats wrong with the motherboard? Is it too cheap speaking of quality or simply not as functionnal as it could be?
No issues sticking to the Intel board in case you cannot get a board from a different manufacturer.. My only grudge with Intel original boards are that they are stripped down on features, have a very basic BIOS and do not overclock that well.. This board though takes care of the feature issue and has a good layout.. But for the money I personally would surely want something's more..
