This is probably a stupid question but here goes. I have an older PC. I ran SiSoft and it tells me I have an AGP slot with version 1.0. Will any of the newer graphics cards work in this type of slot? I wanted to get a Radeon 9600. Thanks,

I guess what I am really asking is this: I already bought a Radeon 9600. It looks like it fits into my AGP slot except the way the board is set up. I have to turn the card around and put it in backwards to get it to fit in. I thought AGP 1.0, 2.0, 4.0, and 8.0 were all backwards compatable? Did they make a mistake at the factory and put the thing in backwards? Or is 1.0 simply not compatible with other versions?

There are three agp versions, agp1.0, 2.0, and 3.0. There are four agp data transfer / voltage formats, agp1x, agp2x, agp4x, agp8x.

agp1.0 = supports agp2x and agp1x cards
agp2.0 = supports agp4x and agp2x cards
agp3.0 = supports agp8x and agp4x cards

Each version is backward compatible one level, which is why an agp3.0 card (yours) will work on a agp2.0 mobo (agp4x/2x). If your mobo is version 1.0, it may fry your vid card because its gonna give it 3.3V and the card won't be able to handle it.

I noticed when ati announced the 9700 that they said it would run on agp2x mobos (not to be confused with agp4x/2x mobos), but I don't see that on their website any more. May have been a typo.

Somebody jump in if I've got anything wrong here.

Thank you all. I guess it is time for a new computer.
