Do you see any difference between these two images? If not, look closely.
 

Take a look at Image 1.  Focus on the decals, the beacons on the top deck, and the missiles hanging under the wings in the first image. You can't really see them, can you? They are all fuzzy.  Now, look at the second image.  Can you see that dramatic improvements in the jets' details?  The decals are all readable, the missiles can be deciphered as missiles, and many other elements can be seen.  The overall fuziness has been lifted!!

You may ask,
How was this done?
The simple answer is the Accelerated Graphics Port

What is the Accelerated Graphics Port?

The Accelerated Graphics Port (AGP) interface is a new platform bus specification that enables high performance graphics capabilities, especially 3 dimensional, on PCs. It is a dedicated bus from the graphics subsystem to the core-logic chipset.  This new bus shifts the memory requirements for the 3D portions of a graphics subsytem from the local frame buffer memory to main system memory

The benefits of AGP include:

• Peak Bandwidth 4x the PCI bus, and higher sustained rates via sideband addressing and pipelining, and more data transfers per clock
• enables graphics cards to execute texture maps directly from system memory instead of forcing it to pre-load the texture data to the graphics's cards local memory - Direct Memory Execute of textures.
• Reduced Contention with the CPU and I/O devices for bus and memory access. The PCI bus serves disk controllers, LAN chips, and possibly video capture. AGP operates concurrently with, and independent from, most transactions on PCI. Further, CPU accesses to system RAM can proceed concurrently with the graphics chip's AGP RAM reads, because of so-called out-of-order and queuing hardware support in the chip set. So in spite of heavy access from the graphics chip, there should be no audio breakup or other CPU degradation.
• An "extra port" to the graphics chip for memory access, so it can concurrently read textures from AGP memory while reading/writing Z-values and pixels from local memory.  Allowing the CPU to write directly to shared system AGP memory when it needs to provide graphics data, such as commands or animated textures. Generally the CPU can more quickly access main memory than it can graphics local memory via AGP, and certainly faster than via the PCI bus.
• Enables new classes of applications on the PC such as 3D CAD/CAM, data visualization and 3D user interfaces
