    Are there any current versions of the ViDock that will run a 5850? It has pretty low power requirements compared to the 5870.

    A desktop HD5850 is a huge boost over a desktop 8800, let alone a mobile one.

    I hear a ViDock is to come out which will support these more powerful videocards.

    Current ViDock has chassis limits and uses a x1 expresscard link. If can overcome the chassis limits (ViDock 4?) the HD5870 would only be worth considering if you can plug it into an expresscard 2.0 port. The bandwidth limitations means it can't really spread it's wings. Latest PM55 chipset claims pci-e 2.0, but not clear if the southbridge and therefore expresscard port is 2.0.

    A DIY ViDock overcomes the chassis limits, and if you have an expressport/mPCIe combo being port1 and port2, can combine them to do a x2 link (x2 1.0 or x2 2.0 in newer pci-e 2.0 systems).

    There are benchmarks in that thread that show the 5800's doing decently well at x1. Even if it is throughput limited, it's a nice step up from what I have.

    a 5800 at x1 beating out an 8800 at full bandwidth?

    i seriously wonder.

    x1 2.0=great, x1 1.0=poor. See HD3850/HD4870 PCI-e scaling analysis at x1 1.0, x2 1.0 an x16 2.0 and HD5870 pci-e scaling.

    Current notebooks' expresscard port is x1 1.0, which we've found has > 50% performance drop over x16 2.0. Next gen of notebooks with expresscard 2.0 will have x1 2.0 performance which can allow a HD5870 to spread it's wings.

    seems like x1 2.0 is still a giant performance drop in some games (cod4, crysis) but it does look like it could still beat out some higher end mobile cards depending on the application.

    pretty slick.
