Hello lovely people from EP!

So I got me a PS3 slim, which is hackable, and I was wondering what'd be the best thing I could do with it.
I know of the 3.55 OFW -> Rogero 4.65 method, but are there better choices? What's the simplest and/or most effective?

I want to hack it and still be able to play actual physical copies of newly released games, like GTA V. Is it possible? Even if I have to sacrifice the online possibilities (which I know is quite likely)

My PS3 has 3.15 OFW, so it can run CFW.

Any tips would be greatly appreciated!
