I’ve taken the system information example from here ( http://bbs.applescript.net/viewtopic.php?id=11372 ) and added some additional infos: GPU, VRAM and Number of CPUs. Added them to the CPU temp and screen res info for my little first project.
Anyway, now an additional question that would really add to my project. Is there a way to get the default web-browser? That would be really useful.

PS: Here are the additional sysinfo-lines:
set number_of_cpus to do shell script "system_profiler SPHardwareDataType | grep 'CPUs' | cut -c 23-"
set gfx_chipset to do shell script "system_profiler SPDisplaysDataType | grep 'Chipset' | cut -c 22-"
set gfx_vram to do shell script "system_profiler SPDisplaysDataType | grep 'VRAM' | cut -c 21-"
