Sell it. A PlayStation 3 that can play PlayStation 2 games is called a PlayStation 3 80 GB (GB Stands for Giga-Byte) The PlayStation 3 80 GB, right now, costs $500. Since the PlayStation 3 just came out a year ago, and thats when you bought it, your system is worth about $200 dollars. If you got it six months ago, its about $300 dollars. If you got it in the past five months, its about $350. Seriously. Hope that helped.
