PCI Express - Semantics 2004-08-13 - By Roman Ormandy
Back
PCI Express is not realy a bus anymore but a point to point communication
network like internet itself. Intel does not emphasize this too much just
yet, but it will become more clear with PCI Express AS which is a full
switching fabric, very suitable for parallel execution of next generation of
software.
In any case even regular PCI Express is great, get it.

Dave,
PCI Express is one type of bus that connects the system and peripherals
together, referring to the slot type on the motherboard and edge connector
on the accesory card (along with what data and how it is carried along the
bus). The GPU has little to do with it apart from whether it would make
sense from a performance point of view to connect it via a PCI-Express bus,
or throttle it by connecting it to, say, an AGP bus.
PCI-Express is not just for graphics cards, I've seen motherboards with 5
PCI-Express connector slots on them but I think you have trouble if you put
5 graphics cards in them!

So "supporting PCI-Express" means that at some time in the future you
could
replace the GPU on the graphics card (for which I am interpretting
"slot" in
you explanation below) with one that is designed for PCI-Express??
If that is the case, then this is a bit duplicitous as most users don't
replace the GPU's on their graphic cards. I find this hard to believe.
Are
you referring to something else?
Nevertheless, performance wise, what are you NOT getting with a
PCI-Express
"supported" graphics card as opposed to a true PCI-Express graphics
card.
The "supported" cards all boost that they have 16 pixel pipelines which
I
thought was at the core of PCI-e.
Thanks,
Dave Angelini
