Was W7 an N version too? Otherwise it should only end up an N version cause someone installed it by mistake
And if so you could reinstall W10 with a non-N version. Of course that might not be worth the effort but it seems weird that you'd have an N key.
I wouldn't bother with the extra money for the extreme CPU myself. Not worth $30 in performance. Q9550 is still relatively useful. Though if you're on a DDR2 motherboard it's crippled a little. But that applies to the Q8200 too anyway.
Better double check that the board can handle it though.
