I am contained by the proccess of in your favour for a graphics card. What is the difference between AGP & PCI?
Answer:
Before you buy a topical Graphic Card, make sure that your Motherboard support PCI Express(PCe) or AGP ?
If your motherboard support PCe next buy one, don't buy AGP.
If your motherboard support AGP then buy one, don't buy PCe.
If you plan to buy a current PC, then buy PCe, don't buy AGP. why ? because AGP's something like to vanish / antediluvian technology.
And beside that, PCe' fully supported by Direct X 9 and AGP not. This will give you a better graphics contained by gaming/graphical experience.
The best one for now' PCI Express / PCe.
Second one's AGP (about to vanish). third one' PCI (old one).
Here's some explamation for them :
PCI EXPRESS / PCe
is an implementation of the PCI computer bus that uses existing PCI programming concepts, but basis it on a completely different and much faster serial physical-layer communications protocol. PCI Express was formerly particular as Arapaho or 3GIO for 3rd Generation I/O. PCIe transfers data at 250 MB/s per lane to a maximum of 32 lane, a total combined transfer rate of 8 GB/s. It must be noted that PCIe is competent to transfer notes in both directions at once (full-duplex). This effectively doubles the facts transfer rate allowing 500 MB/s per lane giving a total combined verbs rate of 16 GB/s when 32 lanes are employed.

AGP / Accelerated Graphic Port
is a high-speed point-to-point pipe for attaching a graphics card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics. Some motherboards own been built near multiple independent AGP slots. AGP has almost completely be phased out in favor of PCI Express.
Advantages over PCI
As computers become increasingly graphically oriented, successive generation of graphics adapters began to push the ends of the PCI bus, leading to the nouns of the AGP bus, dedicated to graphics adapters. Most motherboards manufactured since the overdue 1990s include either an on-board integrated AGP adapter, or a physical AGP slot into which a separate AGP-based graphics card can be inserted.
For the requests of modern graphics adapters, the AGP bus is superior to PCI because it provides a dedicated pathway between the slot and the processor, allowing for faster communication between the two. AGP also uses sideband address, meaning that address for packets is carried outside of the packet, so the entire packet does not have need of to be read to get address information. In addition, to nouns a texture, a PCI graphics card must copy it from the system's RAM into the card's framebuffer, whereas an AGP card is capable of reading texture directly from system RAM using the Graphics Address Remapping Table (GART). GART reapportions main memory for texture storage, allowing the graphics card to access them directly.
The two principal reasons graphics cards next to the PCI interface are produced is that first they can be used in nearly any PC, as particularly few modern desktop PCs do not have PCI slots — though some motherboards beside built-in graphics adapters lack an AGP slot. Second, a user next to an appropriate operating system can use several PCI graphics cards (or several PCI graphics cards in combination near one AGP card) simultaneously — to give plentiful different video outputs (for the use of many screens). This cannot be done beside AGP 1.0 (early AGP 1x and 2x) and AGP 2.0 (AGP 4x) cards, because they do not support more than one AGP Master (videocard piece) per AGP Target (chipset piece). However, AGP 3.0 (AGP 8x) does support more than one AGP Master per AGP Target; but very few PC (if any) motherboards are equipped near more than one AGP slot, but RISC computers, like HP AlphaServer GS1280 can enjoy up to 16 AGP slots, AlphaServer ES80 up to 4 AGP slots and AlphaServer ES47 up to 2 AGP slots in a single system.

PCI / Peripheral Component Interconnect
The Peripheral Component Interconnect, or PCI Standard (in practice almost other shortened to PCI) specifies a computer bus for attaching peripheral devices to a computer motherboard. These devices can pinch any one of the following forms:
* An integrated circuit fitted onto the motherboard itself, called a planar device within the PCI specification.
* An expansion card that fits in sockets.
The PCI bus is adjectives in modern PCs, where on earth it has displaced ISA and VESA Local Bus as the standard expansion bus, but it also appears surrounded by many other computer types. The bus will eventually be succeeded by PCI Express, which is standard within most new computers, and other technology.
The PCI specification covers the physical size of the bus (including wire spacing), electrical characteristics, bus timing, and protocols. The specification can be purchased from the PCI Special Interest Group (PCISIG).

AGP have a faster 'bus' architecture-(faster data xfer) however the contemporary PCI express is better than the old 8x APG slot so if your m/b supports- be in motion PCI express, if not, travel AGP over PCI.
PCI uses the system board bus to move video where as AGP allows it to direct accss the cpu, haas its own CPU and I persnoally use the GForc FX55 beside 256 megs of ram on the card itself which will speed you graphics to an amazing speed, whether its database work or gaming AGP rules over PCI when psyche comes to rendering speed of the graphics
First, PCI and PCI Express are two different things. PCI video cards are an older standard and mostly, aren't found anymore. AGP is still widely used, but PCI Express is the "new hotness" for video. Depending on how old your motherboard is, it may one and only have an AGP slot, and not PCI Express. They are different contained by size, so make sure you know which slot your motherboard have first before you buy; otherwise you may enjoy a card that you cannot use.
AGP's bandwidth on the system bus is between 256 MB and 2 GB, depending on if you use AGP 1X, 2X, 4X, or 8X. Again, this is dependent on what your motherboard will support. PCI Express has a complex bus bandwidth that ranges between 512 MB and 8 GB, in duplex mode.
Hope this help!
