Would like some opinions on a few things

I’ll getting a new computer in the next couple of days and have been thinking about how to set it up. So I thought I would ask a few questions and get some opinions on a few things First the specs of the new computer are ASUS Desktop * Intel Core i5 3470(3.20GHz) * 10GB DDR3 at 1600MHz * 2TB SATA HDD Capacity
