Explain Sisoft Benchamrk results ?

[Smudge]

Hi there,
When I try to get 3D benchmark results and have my system analyzed, it returns that it cant analyze due to certain components installed .. i went to mad onion & nvidia sites to get analyzed neither gave me results.

The manufacturer sent me SiSOft Sandra info: I don't know if its good, bad or average. It's greek to me. Please let me know ?
CPU benchmark -
Dhrystone ALU 3908 MIPS
Whetstone FPU 1912 MFLOPS
CPU Multi Media -
Interger 7650 it/s
Floating point 8733 it/s
Drives-
HD1 - Buffered Read 79 MB/s
HD 1 av.Access time 8 ms
Then there is a Quake III - record Avg FPS 146.4 - I think that might be faster now since I after got the system, I upgraded my Nvidia drivers to the Xp detonators.

System specs
Athlon 1.4
Asus A7M mobo 761 chipset
384 DDR sdram
Nivdia Geforce 3 64 mg
SB live 5.1
Xp home edition ?? Could the OS be conflicting with their analyzing it at these free benchmark sites ? Regardless, I'm enjoying this computer, but would like to know more about the SiSoft ratings of it.
Thanks, Rom
