Sysinfo may be unreliable, but its unreliable for all hardware, so theyre on an even keel.
I actually disagree here - its easy to game a known bench-marking tool when you know and have the ability to tweak to improve the results - (not that this is necessarily a bad thing). With regular 68k the statement holds, but not when you add an FPGA cpu into the mix.
Id be more interested in looking at how things run. Speed of rendering Lightwave scenes, emulation. Things that a regular Amiga would struggle with.
Real world usage is what counts - bench-marking really just gives you a general idea.
