I have

Card name: ALL-IN-WONDER 9200 SERIES
Manufacturer: ATI Technologies Inc.
Chip type: RADEON 9200 AGP (0x5961) 256Mb

Need to upgrade to a equivalent 512Mb or higher card any suggestions

Second question what's he difference between AGP & PCI & PCI Express?

The Peripheral Component Interconnect, or PCI Standard (in practice almost always shortened to PCI), specifies a computer bus for attaching peripheral devices to a computer motherboard. These devices can take any one of the following forms:
An integrated circuit fitted onto the motherboard itself, called a planar device in the PCI specification.
An expansion card that fits into a socket.

AGP 1x
A 32-bit channel operating at 66 MHz resulting in a maximum data rate of 266 megabytes per second (MB/s), doubled from the 133 MB/s transfer rate of PCI bus 33 MHz / 32-bit; 3.3 V signaling.
AGP 2x
A 32-bit channel operating at 66 MHz double pumped to an effective 133 MHz resulting in a maximum data rate of 533 MB/s; signaling voltages the same as AGP 1x;

AGP 4x
A 32-bit channel operating at 66 MHz quad pumped to an effective 266 MHz resulting in a maximum data rate of 1066 MB/s (1 GB/s); 1.5 V signaling;
AGP 8x
A 32-bit channel operating at 66 MHz, strobing eight times per clock, delivering an effective 533 MHz resulting in a maximum data rate of 2133 MB/s (2 GB/s); 0.8 V signaling.



The Accelerated Graphics Port (also called Advanced Graphics Port, often shortened to AGP) is a high-speed point-to-point channel for attaching a graphics card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics. Between 2004 and 2007, AGP was replaced by PCI Express.

PCI Express, officially abbreviated as PCI-E or PCIe, is a computer expansion card interface format introduced by Intel in 2004. It was designed to replace the general purpose PCI expansion bus, the high end PCI-X bus and the AGP graphics card interface. Unlike previous PC expansion interfaces rather than being a bus it is structured around point to point full duplex serial links called lanes. In PCIe 1.1 (the most common version as of 2007) each lane carries 2500 mega-bits per second in each direction. PCIe 2.0 doubles this and PCIe 3.0 doubles it again.
