i'm pretty sure i've read that the backwards compatibility only works as long as it does not create a bottleneck, i.e. the processor kicking out more data than the old pcie can handle.
i do have a question. why as it that the mac 8800's are so slim? i've been lead to believe the other ones are thicker because they need larger heat dissipation components.
That's because the new 8800's have a smaller gpu core resulting in less heat and a smaller foot print. Same for the PC versions. I'd love to have one but the new card from them should have 2x of these on one. :)
It's fully backwards compatible, both from the device (PCIe2.0 GPU + PCIe1.1 mobo) and from the host (PCIe2.0 mobo + PCIe1.1 GPU). As for actual used bandwidth, it's much like hard drives: we've barely passed saturating x8 PCIe1.1 (even though x16 has been around for a while), so the issue must not be in the spec, but rather in Apple's own hardware implementation. Remember when there used to be Apple-specific GPUs from nVidia/ATi? My guess is that sort of design choice is coming back to bite, now with next-gen GPUs.
Kudos to Apple IF they take the initiative to resolve the issue. But if not, welcome to the world of DIY troubleshooting, where PC builders have been identifying faulty components, tracking down liable manufacturers, and dealing with hours of support tickets and RMAs for many, many years. ;)
HP has had plenty of time to fine-tune its finger-friendly TouchSmart software, and now, its newest model, the TouchSmart 610, ushers in a fresh design, highlighted by a hinge that allows the display to slide down and lie nearly flat.

The 8800GT is a newer modle with a smaller heatsink while the rest of the 8000 fmaily has larger heatsinks, this is standard for all hardware systems.
@Chris von Eitzen: thank you. i was looking at an older model, that explains it.
