i plan on using an Eye Tech TM4 eye tracking device with grid2 software. wonder what computer would offer best performance. you have the eye tracking software continually running and multiple windows on the net plus music and music or video downloading. i also download and service payroll for my care givers. it will be used at least eight hours a day. budget on laptop is $2000. really want speed and reliability and was considering a gaming setup because they seem to have everything so and maybe asus g73jw a1 ?
