If this can help, on Windows you can keep both LR4 and 5 working. So if an image gets messy, you can still work it on your LR4 installation.+1
And BTW I would never go back to LR4, I've gained lots of productivity when I switched because of LR5's new tools.
Ten minutes with LR5 had me 100% convinced. It's an incremental, though powerful upgrade.
The Radial Filter alone was worth the price of entry for the way I work.
The more I use it, the more I use it, the scope of its usefulness being revealed with every session.
FWIW I use LR on both Windows 7 and OSX Mavericks machines with no issues.
