    with different encoding method, presumably the controller chip will need to understand both for backwards compatibility. wouldn't that drive the cost of motherboard and graphics card up?

    Not really, it's just another fixed function in the silicon. The fact that it's faster already pushes up cost more because of the quality of raw materials needed to make the faster process reliable.

    +1 That was the biggest pain in the arse about AGP -> PCI-E.

    But the article says that it will be cheaper to make as it draws less power...

    Yeah I'm still pissed about how my old PC basically became obselete three months after I bought it

    Nice article Rich, it's good to read some more technical stuff every once in a while.

    Interesting - more bandwidth for the future console ports.

    No it says that 8GT/s is cheaper than 10GT/s, yet provides the same usable bandwidth. ;) It's a relative amount :)

    Ah got ya. 8GT/s cheaper than 10GT/s but still more expensive than the 5GT/s of PCIe 2.0. It was early. :D

    One thing though, are graphics cards close to maxing out the usage of PCIe2.0? I am a relative noob in this respect.

    I'm thankful they didn't increase power consumption again. 150W through the slot is plenty, and considering many enthusiasts own a power supply with at least a 6 pin connector, so we should be fine (Plus, I don't think people are going to be running 580 GTX cards with the current limiter off on 400W units)

    If I recall right, they didn't even max out PCIe1.1

    i don't think even gtx580 are hitting PCIe 2.0 limits.

    i shall take this upon myself and test :D if i place my sound card in 2nd 16x slot on my mobo, i'll force main GPU to run at 8x mode, which i can then test to see if performance is being limited. my guess is gtx580 won't even use full 8x PCIe 2.0 at the moment.

    I'm sure I've seen tests somewhere that showed the GTX 480 wasn't restricted by x8, so as we already have x16 waiting to become useful, who on earth is going to make use of this at any point before 2015?

    So since graphics cards arent saturating 2.0 specs I would assume this is more aimed at highend Raid SSD PCI-E devices? at least for the time being....

    Actually there's an SSD still on the front page that could make use of it... I guess it will trickle down to us little guys eventually though.
