last gen core i5-4460 but it's still an i5, non overclockable, but that's really fine. It's not necessary at all. I am personally still on a Core i5 from several generations ago (Sandy Bridge) but it still carries its weight.
Basic Gigabyte mATX motherboard.
8 GB of Dual channel DDR3 memory (2x4 to properly utilize dual channel)
120GB SSD from Adata. The logic here is to start out with a boot drive that's speedy and have a bit of storage right off the bat, and you can always add additional storage later on. It't not that expensive to add another 1TB of regular HDD for like $40, but for the sake of this build I left it out. Once you go SSD for boot drive, you generally don't go back.
The prize of this build allows for a 4GB R9 380 card from PowerColor. 4GB of VRAM for "futureproof" as more games can take advantage of more VRAM in the future. More powerful than the GTX 950 which only comes with 2GB VRAM, among other things.
Basic case from Zalman. Comes with USB 3.0 on the front, always nice.
500W EVGA PSU, it's 80+ Bronze at least and it'll support the R9 380.
Final price, after shipping and mail-in rebates: $547.70
Does not include peripherals (KB, mouse, monitor) and OS.
