I already have a 850w EVGA Psu along with kb/m+monitor.
I forgot to ask, do you need any peripherals besides what you listed that you had?
PCPartPicker part list / Price breakdown by merchant
No other peripherals needed.
bump the ram down to 8g and youre in your price range. Im not 100% sure about the settings but from what ive been reading, the 6600k and the r9 390 are plenty
It recommends an i7 and 16gb of RAM. Also, it is way better optimized for Nvidia.
You won't max it out or use many if any mods due to 32 bit engine.
Fallout 4 minimum RAM is 8GB
