Got it today, installed it, and as expected, everything works fine now (including the 1.5TB HDD; that will save all my storage woes I've been having recently for a while).

Good thing - fan is quiet, though I didn't try to listen hard or anything (PC on a whole does seem to be a tad bit louder than before when I unplugged the GPU fan), so no more downclocking bullchocolate - yay!
Not so good thing - performance improvement over the 4670 is really small.  Tried Crysis on Very High settings, 1024x768 with no AA and I get around 20-30fps.  Playable, but that's about it really.  Expected around >30fps for that, especially for a 2+ year old game...

And this Samsung 1.5TB HDD has the annoying clicking startup issue:
