I watch a lot of mecha series and what Jafo is trying to build is GN Armour, or Armour Mobile suit, or artillery type/Destroyer type computer.
In multiplayer terms we call such a build the "Overkill the noobs build." There usually over powered monsterosities that are not green to the environment because the performance per watt is not fully utilised by the games we play (wait for dx12 for you GTX 9XX) and they draw an immense amount of power to run all those components at maximum speed.
In mecha series GN ARMORs tend to be slow moving but heavy on defence with long range offensive capabilities. In this case we are talking about high frame-rates, or unlocked frame-rates that allow sniping easily at an incredible range. Coupled with a monitor with a an insanely high refresh rate then you get a long range killing machine He can also turn off virtual memory with high amounts of ram, rendering such a feature worthless and blaze data through the rams without touching the SSDs for any extras.
Defence comes only in the way of a machine that can run a large screen estate that can set a higher resolution and have a larger glimpse of the battlefield. ARMOUR type units are usually in boss episodes or episodes with cliff hangers that put the challengers through a tough time. Only skill wins here because Jafo won't have so much distraction from bottlenecks.
I have seen first hand what these kinds of machines can do to Noobs when in the hands of a pro online because they will be so much crying about a cheater in the game. Its actually a pro whose skill and assimilation into the game is at its max because of no performance hiccups. Only internet lag can save noobs from "Overkill the noobs builds!"
