"The ASUS v7700 GeForce2 GTS ships with a decent size 3 wires instead the normal two... The extra wire is included because this card has a hardware (temperature) monitoring chip on it to measure temperatures and voltages. I was pleasantly surprised with the v7700 because when physically touching the GPU chip it didn't burn me like other GeForce cards I have played with... This is good because, it later on it will give us better overclocking potential."
