brings about the question tho... what to put in the 1x spot
32-Bit PCI still seems to be the more common thing out there. However there are PCI Express devices coming out into the market.
Creatives X-Fi Extreme Music Sound Card (OEM) come in both PCI and PCI-Express. The funny thing is that it $10 cheaper to get the PCI-Express.
Adaptec jumped on the PCI-Express bus 2 - 3 year back with SATA and SCSI controller cards.
Various other I/O Cards (Firewire/USB/Parralle/Serial) are coming out in PCI Express.
I think it's D-Link that has started doing PCI-Express WiFi Cards.
nVidia Quadro cards come as PCI Express x1 as they don't use the x16 bandwidth.
My co-worker purchased a PCI-Express video capture card for his HTPC.
I predict that in
3 Years time, PCI Express will become more mainstream.
3 to 5 years time, new 32 Bit PCI Devices will be phased out.
5 to 10 years time, 32-Bit PCI Slots will be completely removed from new motherboards. However in the mean time, you will be seeing less and less 32-bit PCI slots. In the last few years new motherboard will only have 1 32-Bit PCI slot
