So, hypothetically speaking - Someone has an old Desktop PC that doesn't have PCIe,
& they want a Super-Recent-Awesome-NameBrand-GPU without upgrading the whole PC.
Which only has AGP & PCI. I know an adaptor from AGP to PCIe is fairly hard (or impossible) to do.
Now, all of this, although insane, sounded quite interesting to me!
SO i looked at various external solutions:
like the ViDock - http://www.villageinstruments.com/tiki- ... age=ViDock
Which unfortunately would require an internal PCI card that gives an ExpressCard port to the desktop.
And of course some internal ones:
Like using http://pinouts.ru to manually wire up a card (Dangerous & UnReliable Sounding)
OR using adaptors like http://www.epn-online.com/page/42574/pc ... ridge.html
However i am unsure if the above adaptor is for PCIe(16x).
So just in case: an adaptor from PCI to PCIe(1x) and into that plug a PCIe(1x) to PCIe(16x) adaptor?
So like this (PCI->PCIe1->PCIe16):
Straight onto the motherboard goes this adaptor:

And into the previous adaptor goes this adaptor:
http://intrl.startech.com/Cards-Adapter ... ~PEX1TO162
![](http://intrl.startech.com/media/products/pex1to162/Small/PEX1TO162.small.jpg)
Thus allowing a PCI-E card to be plugged into a PCI slot.
NOTE: i know that it would require custom housing & power - so dont worry bout that...
but what about bandwidth requirements?
Maybe it would require 2xPCI slots adapted into 2xPCIe1 - which are then wired together to the 1xPCIe16 - thus providing more bandwidth? is any of this even possible???
