Dear Mr. Fierz, I think that you did not make a mistake. The AMD 1.33 and 1.4 Ghz still have no thermal overload protection like your Intel PIV 1.4 Ghz and if the heatsink should ever loosen or the fan motor craps then you would have a nice AMD paperweight. Wait another year and get a nice computer with 0.13 micron architecture and watch how fast Cake++ and your other programs fly. Rajen was partly correct at how much faster the AMD chips are but at 73 watts we are talking major egg-frying temps without overload protection. You did right good buddy. Anyway, the PIV chips do well at video chores. Don't worry about it.
