For those that seek quality over all else then there is only one thing to do, go over the top! This system includes its own 120hz monitor which reduces visual delay in RetroCopy from 20-50ms to 10ms, a must have for those seeking an extra edge.
With 4 cores and 4 hyperthreading cores, RetroCopy can run upto 20 virtual machines at once. The latest graphics card from ATI with DirectX 11 support insures you against the future.
The EX58-UD3R motherboard from Gigabyte is an excellent overclocker allowing you to go beyond 4GHz with the Intel I7 CPU. 6GB of RAM rounds out the system, with this amount RetroCopy will be able to fully utilize all its features with ease.
With this system we use a dedicated power supply from Corsair and a new case. The reason for this is with high end components you don't want them ruined by a dirty power input, good PSU's filter out any noise on the lines keeping your components safe.
This machine would play the latest games at the highest settings without breaking a sweat. If you wanted to save $100-200 you could choose a cheaper video card without it affecting RetroCopy too much.
