AGP Video Cards

Can anyone direct me to a website that shows the different kinds of AGP video cards. I was at a computer auction and picked up a couple of boxs full of odds and ends (Hard drives, CD-Roms, sound and video cards, motherboards,cables etc) I've been checking & testing everything and found that about 90% is is in good working condition (It's not just old junk, some fairly new stuff, like 40 Gig HD) What I would like to know is, what do you look for to tell the difference between the different styles of AGP video cards. Is it a 1X, 2X, 4X, or 8X and can you tell by the chips how many megs of ram it has and if not how do you find out. Thanks in advance for your help.

See if this helps:

Thanks Archer I checked out those sites, they help me figure what kind of cards I have has far as speed and voltage is concerned. I appreciate your help. Now I have to figure out how much ram they have with out going thru all the trouble of installing the cards and the drivers.
