Cheap, but efficient, simply put.
i5-4690K 8GB DDR3-1600 RAM Sapphire R9 280 3GB
This machine can run virtually any game you throw at it and at comfortable settings and frame rates. I didn't run any benchmarks, unfortunately, however I tested out how it handles tasks that my brother would actually be carrying out. The i5 made it great for streaming while playing games such as CS:GO, RocketLeague, ect. It renders 1080p footage at a remarkable speed. While running CS:GO it rests at somewhere around 250-300 fps and I haven't noticed any frame drops at max settings.
tl:dr It is a decant machine made for softcore gaming and occasional editing/streaming.
