    Default whats my bottleneck ?

    i was origanaly able to get my 1.6ghz duron / gf4mx4000 up to 1.9ghz before my comp would crash (fsb158) i switched my video cards the duron/ti4200 box will only oc to 157fsb before 3dmard2k1 crashes but the proccesor seems to be good for more than 160fsb the temps are between 40-46c . what should i change or what could be the actual problem ?

    Your PCI bus probably goes too far out of whack, and some cards tolerate it better than others.

    agreed. the ti4200 is a relatively fast card anyway. I would guess that the bottleneck here would be the chipset and cpu before the vid card.

    Motherboard and Ram possibly.
    KT333 is a good chipset don't get me wrong, I use one myself, but the nForce just destroys it.

    The PCI bus is your problem.
    Those old chipsets use the PCI bus for the north and south bridge's communication link where as chipsets now use a dedicated link.
    Because of this most modern chipsets can lock the AGP/PCI buses, your old chipset must rely on dividers (150MHz FSB is where trouble will usually start; AGP = 75MHz/PCI = 37.5MHz).
    If you have an unlocked CPU you could adjust multipliers downward a step or two and run on the 166MHz FSB and its AGP/PCI divider with chipset (exceptions maybe some ver 1.0 mainboards).
