    I'm trying to use a video card that will suck the power out of the motherboard, possibly limiting its max OC. I'm just trying to get an idea of what card that would be for the future.

    4670 from ati. the performance is almost the same as the 3850 which i have. the 9800gt would be faster though

    Is there one that isn't "energy efficient?" That makes me think it would put less strain on the board.

    Anything higher from the red camp that can go PCI-E power-less?

    I remember reading that. Definitely could be a good card to use.

    I remember reading that there was a 4830 that run off the pci-e bus. No external power needed. I have never actually seen one for sale though...

    Yeah I just looked for one and I can't find one ANYWHERE. Just all reviews. It's basically the polar opposite problem that I normally have :p

    An electrical appliance connected to a power supply will always draw the needed amperage. Meaning OC is not limited by absense of an external power plug, because if the card needs 100W or 150W it will draw it from the slot. The only problem is resistance of the motherboard PCIe power plane and the slot, meaning they will get hot, hotter and even hotter when current increases. Eventually the spot where there's highest resistance will heat up to a point the metal will melt and break the circuit.

    So, no, you can't limit the max OC in this way - unless you count burning the motherboard as a limiting factor.

    If you're looking for the most powerful videocard that doesn't need a 6pin, then your best bet would be the Abaltron HD 4830 'Green Edition'

    http://www.techpowerup.com/reviews/Albatron/HD_4830_Green/

    The Green edition is actually MORE powerful than the stock 4830 with 800 shading units compared to 640 on the standard 4830.

    I won't be needing one of these for a while. Thanks for the input guys, and I'll post a WTB when I'm in need of one.
