Do you mean PCI express? Any video card that uses the PCI bus is going to be so old that it really won't do well. Right now, from what I have read, the best bang for the buck is the Nvidia 6600GT cards. They are around $180 for PCIexpress and $219 for AGP. Leadtek has been very highly rated and so has the XFX. I am going to order the Leadtek AGP 6600GT to replace my ATI Radion 9000 AIW.
