Hey forum! I just bought an Ivy Bridge MBA (love it!!!) and I want to make my old mid 2007 MB (Intel Core 2 Duo) my secondary comp for PPC apps (it is running SL) and Windows XP via Boot Camp (I plan on putting Windows 8 on my MBA when it's released). My MB's performance is terrible. Would wiping the computer have any benefit? If so, what OS will be left there. It's running 10.6.8 but it came with Tiger. Also, is there anything else I can do to help it out? Sorry if any of those questions are dumb, everyone learns sometime .
