This is really a Technical Q & A question but having said that PCI Express will show a better games application or if you are doing some Graphic intensive work.

You really need to list the software and the work that you intend this system to perform and then most likely you will get a better response or at least a more technically correct one.

By the way PCI Express is the new technology and it will be seen on more and more computers as time goes by but the individual components may not be as good as some used on AGP systems at the moment and the drivers while being specifically written for MS Windows may not work all that well under a different OS. It all depends on what you want to do with this computer.

But the claimed PCI X advantage over AGP is speed and it is claimed that PCI X is currently about 4 times faster than the fastest AGP but even then there are not to many applications that can take full advantage of the latest AGP let alone PCI X which may not be supported by some of the older applications.

What you really need to think about here is what you need this system to do and then consider using components that suit your needs. You should forget about the prepackaged systems and go for one that can be tailor made to suit your needs it might have a greater initial expense but will more than pay for itself over the long run with far fewer reboots required and faster running time, meaning you get more done in less time. Again this depends on what you actually want to do with the computer as if it is only Word Processing and a few spread sheets there isn't all that much processing power required.

1st off an actual video card with its own dedicated memory chips will give better performace than a graphic chip integrated into the motherboard shareing system memory. If both solutions are integrated I would recommend the Ati pci express. Neither will effect your applications.
