Computer chips are improving in terms of speed, but the trend now is not the speed, but in efficiency. Chipmakers are into dual core, quad core, for multi tasking. My idea is this: can someone build motherboards that will accomodate 2, 4 or maybe 8 cpu's (old but working chips). The same principle is applied on quad core cpu's (4 old cpu's in 1 mobo). Application: 4 tasks at the same time can be performed by the computer. (Convertible slots are encouraged so different cpu speed and slots...
