One little drawback which i can think of at this moment is, LGA-1156 socket platform will limit your future upgrade path (i.e. if you plan of doing so couple of years down the road).
Now that out of the way, its very capable processor as well, and offers very attractive features (e.g. Hyperthreading, which 750 doesn't offer) at very affordable price, hence making a compelling case for buying this CPU.
