    The VTX is based on the Tahiti LE chipset that are used on the HD7950/7970 cards basically making the VTX a HD7930.
    When overclocked, they are on par with stock HD7950s :)
    So if you value raw performance I would get the VTX, note that the Saphire should run quieter/cooler than the VTX.

    Thanks. I think the VTX does offer decent bang for buck (from reading some more threads here) and there seems to be quite a few happy VTX users around.

    thanks again.

    VTX + After market cooler is what I've gone for. Faster than the Sapphire and cooler/quieter. Stock heatsink is too loud though imo.

    The Sapphire HD 7870 is cooler, quieter....

    VTX3D HD 7870 is about 10% faster clock for clock.

    For Tahiti LE the Sapphire XT is better, OCUK used to stock them, can't see them now....

    After - Idle - 28c, Furmark - 76c, Normal Load (BF3) - 66c, Noise - Silent or near enough not to matter.

    Will post pics later.

    Yeah if you could that would be great.

    Just bought the VTX3D 7870 myself.

    Its tempting to add a custom Cooler

    Comes with rubber grommets, you can buy a 120mm designed for this cooler though which has better ones.

    Yeah it's a bit silly, have the old version in my HTPC on an 8800GT. Effective at least.

    At 12v it is audible, mostly from the air flow with a very slight buzz. At 7v it's very, very quiet; my 5400RPM storage drive is louder.
