I would say that 1.6 is pretty good, actually for some odd reason I updated to 1.7 and any time I would restart the computer from within Win 7 it would hang forever (only show black screen with a white cursor) after the screen that says loading AMD AHCI BIOS but reverting back to 1.6 fixed it, tried multiple times to use 1.7 without avail, even updated all drivers and nothing. So as for now, stick with 1.6 until maybe 1.8 comes out.
