I'm building a gaming PC soon ($750 for the whole thing, including MB and OS) and I had planned to use an i3 4130. I had my dad run this by his friend who's pretty good with computers. My dad's friend (We'll call him Joe) said that the i3 I mentioned would be obsolete in a year. Joe also said that I should get an i5 at least, and probably an i7. I'd only be using this build for gaming (Nothing that demanding, DOTA, MC, Warframe), and school stuff. Joe also said I need 16 GB of RAM MINIMUM, as well as space for 32 GB. I'm beginning to doubt his judgment. Could you shine some light on the situation?
