PCIe x1???

I'm sure just about everything will come out for PCIe 1x evetually...it's just a matter of actually making them! I mean is there any real advantage over PCI?

Absolutely ... YES !!! :)

PCI speeds can't really go any faster without the hardware costs rocketing, and even then no great improvement will happen.
The problem with parallel interfaces is you have to keep a bunch of signals in sync else the data gets read incorrectly.
All very prone to capacitance and inductance problems, but never mind the reasoning.
PCIExpress is a *serial* interface, so only *two* active wires are needed, so it's way easier to go faster .. easier, yup .. easier. :)

Also, PCIExpress *lanes* don't share bandwith, whereas *all* PCI devices must.
The end result being extra speed which also applies to externally connected devices, not just internal. This includes AGP cards too, they will fall by the wayside.

PCIExpress will become the next standard.

OK, I knew PCIe would be the next standard and all, but I mean for today's standards, most PCI devices work fine in PCI slots. So far about the only real limitation is when people use PCI GFX cards...

I didn't realize PCIe was serial... I knew more stuff was going that way due to the speeds(USB, SATA)

Well, if alot of things will use PCIE in the future, why dont they just make more PCIE x16 slots instead of x1?
 
because you don't need 16 PCIe lanes for most add-in cards, you don't even need the 16 lanes for video yet

PCI-X which is, for all intents and purposes, an extension of PCI doesnt cost so much

Hehe back in the day things were serial and then there was the parallel revolusion and now back to a serial revolution hehe

feasbility limit of max number of PCIe lanes
