Third line: "Tarjeta gráfica: NVIDIA GeForce GTX 660 o superior". "NVIDIA GeForce GTX 660" is a proper noun. "o" and "superior" handled as before.

Continuing step by step, replacing each word with three options, ensuring not to change any proper nouns. Words like "Abre", "selecciona", "carga", "configura", "juega" all get their three variants.

Need to make sure that the structure of the sentences remains intact and the meaning is preserved even after replacing each word with three possible options.

Next, I'll check for verbs and adjectives that can be rephrased. Words like "ofrecen" might become proveen. I have to pick three suitable synonyms for each. Also, phrases like "amplia variedad" can be transformed into amplia variedad.
