Noob question on Water Pump

Quick question from a noob on water pump replacement:

I just bought a 2009 328i xDRIVE with semi-high mileage, and I'm going to be replacing the water pump, thermostat, radiator hoses, reservoir tank, and do a coolant flush.

BUT, I'm wondering if the e90 M3 water pump is compatible with this engine? And if so, is it worth purchasing over the stock water pump?


As background, I just noticed the M3 water pump on Turner's site, and it mentions an 'upgraded aluminum impeller' - I don't know if this would improve reliability...see links below.
