AGP

I want to know some things about AGP.
1. What is AGP
2. Is AGP only available on P2 boards
3. What types of AGP are there (agpx1..)

1.) Accelerated Graphics Port. This port is designed with speed in mind. Much faster than a PCI or ISA, and is linked to your main memory for better performance in time of need.

2.) No. AGP can be on PII & certain Socket 7 boards.

3.) Ther are two types, x1 & x2.

Thanx for explanation.
But what are socket 7 boards??

Socket 7 boards are those designed to take non-PII CPU. i.e. AMD K6, AMD K6-2, Cyrix, IDT, legacy Pentium, etc.

A good example is the ASUS P5A board. There are quite a few others out there. Word of warning however, if you purchase a PC Chips board you will get a number of AGP problems.

I cannot decide between Canopus Spectra 2500 and Velocity 4400 video card. I am looking for great 2D and 3d(for games) performace.
Can video card that support AGPx2 work on AGPx1 system?

To my knowledge, no. If the board supoprts x2, I beleive it will support both x1 & x2 cards, but not the other way around. Double sheck this howerver, I may be mistaken.
