I've added some new goodies in the Tools section. I should note that the DSDT system seems to add 10C to CPU temperature readings within OS X. Working on this. Here is an overview of the new Tools package:
Benchmarking:
AJA System Test (better hard drive speed testing than Xbench/Geekbench)
Geekbench (general benchmarking, share your score!)
Xbench (general benchmarking, share your score!)
Cloning Kit:
SuperDuper! (makes a clone)
Chameleon (makes the clone bootable, just install this to the cloned drive after using SuperDuper)
Memory Testing:
Rember (Mac runtime version of Memtest)
Memtest (Memtest86+ bootable ISO - burn to CD or DVD, do 6 passes with Zero errors to ensure 100% functional RAM)
Processor:
MSR Tools (shows a bunch of detailed info on your CPU, such as voltage, clock speed, etc.)
CPU-X (Mac's equivalent of CPU-Z, lots of CPU info)
Termianl HOWTO (Terminal test for making your CPU Cores go to 100% load to test stability and monitor temperature)
Temperature Monitor: (temps may read 10C higher than BIOS due to bug in DSDT)
Temperature Monitor (main app, install this first)
Temperature Monitor Lite (menubar version)
Temperature Monitor Widget (Dashboard version)
