Whats the difference between PCI and PCI-E graphic cards?
Answers:
No, you can't put a PCI-E card into a computer that only takes PCI. They're two very different slots. The E stands for "express".

For video, your computer may have an AGP slot. I wouldn't be able to tell you without knowing what motherboard you have.
PCI and PCIe are not the same thing. It's kind of like how Windows 3.1 and Windows XP are both Windows, but are completely different other than that.
You can have both most people, but if you have a older computer you will only have PCI slots and so that is all you can run in terms of graphic cards.
PCI is older Techology that is still used today but most motherboards now come with both PCI and PCI-Express, I run a modem in my PCI slot and have a Geforce 7900 gt PCI-E card.
Why should I care about PCI-Express?
There are two main reasons to care about PCI-Express: 1) PCI is now an old standard dating back to the early 90's and no longer fits our needs in terms of speed/performance. 2) AGP also is in a similar position as PCI now, and chipset manufacturers are killing AGP motherboard support in favor of the much faster PCI Express interface. This means you are looking at a forced transition in the graphic sector, thus you really don't have a lot of choice in the coming years.
While we've spent plenty of time and energy improving the speed of processors, memory, and other parts of the PC we've done virtually nothing with the main connection betweern many devices-PCI. As such we are stuck with a technology in our PCs and Servers that still runs at the speeds and bandwidth we were comfortable with in the 90's. PCI as we know it is holding us back - it is a bottle neck - a limitation to the maximum performance of our systems.
We all want the most from our PC. To get the most out of our PC we must remove all bottlenecks (obstacles to performance). To that end we must turn to the next best alternative: PCI Express.
