Just because you have an SSD doesnt mean you can skimp on the HDD. Theres no real reason for green drives in any application (IMO). Also WD are very expensive given their competitor Seagate is just as good and significantly cheaper.

Despite costing less, this drive is faster.
Speaking of overclocking, you will need an aftermarket cooler if you want to do anything significant. This is the budget cooler to get, and should support moderate overclocks on that 3570k.
