PC gamers' lament... I played Arkham Asylum for PC (I don't have 360 or PS3... just a Wii) and it ran smooth as butter. But, I just found out my CPU isn't even close to the minimums for Arkham City, and my GPU is now the bare minimum. So... do I spend $1,000 USD for a new gaming rig, or get a used PS3 to play this. Decisions, decisions.
