Bonjour à tous

Éternelle question! Que choisir! J'ai sur ma bécane (Dell Dimension 9100 avec Intel double cor) une Nvidia 7800 GTX et pour certain jeu c un peu juste.
Toutes suggestions seront les bien venus
Merci à vous

ATI HD4850, en vérifiant ce que tu as comme alim (mais bon, si ça fonctionne avec une 7800GTX, ça devrait le faire avec la 4850)

ATI HD4850 est vraiment bien niveau qualité/prix

Là ATI HD4870 n'apporte qu'environs 25% d'efficacité en plus ( de ce que j'ai lu ) pour un prix bien plus élever ...

Merci pour la réponse.
C'est une alim de 375 W et voici toutes les spécification de la machine.Depuis j'ai rajouté de la RAM et je suis maintenant 2GB.
Si tu penses que cette ATI HD 4850 est bien et qu'elle peut supporter mon système et en plus elle un peu moins cher que les autres, alors je l'achèterai.
