La carte graphique est un point important, je sais. Mais ma question est simple. Sachant que le prix du HP est en rabais à 1049.96 et que le Gateway est en rabais à 799.96. Qu'elle est le meilleure choix qualité/prix. Le vendeur ne jure que par le Gateway... Cependant, je dois admettre que je n'ai jamais eu de penchant pour HP. Plusieurs me conseil HP pourtant. Je voudrais savoir qu'elle carte graphique est plus performante selon vous et surtout, quel PC me suggèrez-vous?
