Quel carte graphique pour PC bureau HP p6243 ? svp

Bonjour,
J'ai beaucoup de difficulté à jouer online (swtor) avec des graphismes corrects. Mon ventilo fait un bruit d'hydroglisseur.. Apparemment j'ai une alim 300w et une CG nvidia gt220. A mon avis c'est bien dépassé, mais avant de racheter un pc je voulais savoir si je pouvais simplement changer de carte par miracle?
