Bonsoir à tous,

Je suis heureux possesseur d'un Macbook et je souhaite m'orienter vers un nouvelle iMac pour le travail.

Mais j'aurais quelque questions d'abord avant de sauter le pas car j'hésite entre le modèle 21" et 27" milieu de gamme.

Une question qui me tracasse est pour le jeu vidéo, je me demande si le fait de choisir un 21" ou un 27" influe sur la qualité graphique du jeu (exemple Portal 2) ?

En fait je me demande si la carte graphique va supporter la résolution du 27" ? ou est ce qu'il est mieux de jouer sur un 21" avec une résolution qui sera plus basse ?

Ensuite je souhaite par la suite brancher mon iMac en HDMI sur une TV lcd 82 cm et je me demande si le mac gère les plus grosse résolution ou est ce que je serais bridé ?

Edit: a priori les performances de la carte réponde a ma question

Et enfin que vaut la carte graphique HD 6770M ? Est ce suffisant pour faire tourner correctement Portal 2 ?

Merci à tous pour vos réponses car j'hésite vraiment à me prendre le 27" comparé au 21" ^^
