I use this as my primary computer, I use it for 3D modeling, game designing, programing, and web designing.
With the custom watercooling loop from EKWB I overclocked the i7-860 to
3.94GHz 4.21GHz from 2.80GHz (it's gotten to 4.5GHz but becomes instable after a few hours), and the temperature is sitting at about 30°C idle and 60°C full load.
The GeForce GTX 760 is overclocked to 1500MHz with 7000MHz memory clock. The GPU gets about 50°C.
I also installed a LED strip from SUPERNIGHT and use a 44-key controller to control the lighting effects.
