I have no idea... that 170 is going to be pretty attractive to any school outside of the top 20, regardless of your stinky GPA. I think you have a shot at USC, but you are going to have to bring it in the rest of your application.
I'd apply to a ton of reach schools - you never know how they will treat this level of split. 170 basically places you in the T14, I'm sure theres at least one that may take you. Also, I'd apply to a bunch of schools in the region you want to live/work, even if lower ranked, to snag big scholarships.
In the end, this is all speculation. Just make a perfect application, apply, and see what comes.
