To Vista or not Vista. That's a question

Hmm.. since Vista is cracked by pirate group Pantheon, I am thinking of changing into Vista, and test the power of Vista myself. But 1 thing is I am quite of a gamer, so I am kinda afraid because of the incompatibility issue. Another thing is ram. My pc is equipped with 1GB ram... so confirm not sufficient for Vista. But the Aero glass effect and so on really attracts me... If any vista user out there got some advice that can persuade me straight format my xp and buy another 1GB ram.. come and persuade me now
haha
