Very true across the board Greebo .
I have 2 identical systems and they both act totaly different .
1 system will clock up to 4.5 in 100mhz steps and be stable all the way and the other dosnt like anything but 3.0 or 4.0 ,, no other settings are stable .
One of my 8800gtx's will clock to 645 and the other hangs at 620 max even tho they were bought at the same time and have concurrent serial numbers .
I guess that when you put billions of transisters in a computer case there is bound to be variances .
