No voy a abrir otro tema para una pregunta. No tengo mucha idea de esto, y le he estado dando muchas vueltas.

El tema es que la 5770 se me ha quedado muy corta para 1920x1080. Tengo 180 € para gastar.

Principalmente es para jugar junto a un AMD 955 (3,6 ghz) 8 gb ram.

No sequé hacer entre estas dos. Sé que la AMD tiene más memoria, y tiene 256 bits. La otra 192 bits y 6008 MHz (effective). También me gustaría saber si con mi fuente de 500w normalita tengo suficiente. (BMOVE 500W).
