To OP
I dont know why everyone always mentions FPS shooters. Do some fun and productive things like Vista Pro, Pixel Pro, Image FX, Photogenics, etc.. still good tools til this day.
And lots of fun emulation you can do to with that speed...
Really need an FPU though..or Winuae. The software you mention really shines on a 24 bit high res screen with a fast maths crunching cpu, and Winue fits the bill
