Choisir une nouvelle carte....

Bonjour à tous,

J'aimerais choisir une nouvelle carte graphique, mais je ne sais pas trop quoi prendre.

En effet je ne joue pas beaucoup sur PC mais seulement sur des jeux de stratégie. Comme ROME TOTAL WAR 2 va sortir tout bientôt j'aimerais un peu booster mon PC avec l'ajout d'une carte graphique de milieu de gamme assez performante.

Voici la config de mon PC:
