Yup, didn't make much of a difference running their L2 Benchmark..
All I can say for seti optimisation:
Full FSB + Agressive CAS2 timings and Ultra Turbo Ram settings
Turn off uncessary things in a bios (Refer to a bios guide and disbable and enable whichever is necessary)
Use CLI Version of Seti(Pretty sure you all know that)
That's like the only secrets there are to this..
