AGP 1.0 vs. 2.0

If you go through the index, you'll find my other post addressing the problem that is inspiring this post.

What is "AGP 1.0" and "AGP 2.0"?

I ask because I may have an incompatibility problem between a video card and M/B. But I don't know the basic difference between 1.0 and 2.0. All data I can find on motherboards refers to "1x", "2x" and "4x", but I presume that those are not what I am refering to.

My main problem in asking this is I do plan an upgrade in teh future, and since none of the specs I've seen say "AGP 2.0", as a software box might, I'm worried I'll grab a board that won't work.

Can anyone shed some light?

Well, that's what my problem is - I have an AGP card that's not working right, and it MAY be due to AGP incompatibility - though I can't figure out WHICH AGP Bus I have (Sandra lists "PCI/AGP" bus as "2.1", but I believe that's just the PCI bus).

Maybe I'm in the 0.1%, but I'm trying to get conformation on this...

The difference between AGP 1.0 and 2.0 is that 2.0 offers higher voltage to the video card. GPU's are going the way of CPU's in terms of voltage- they are wanting a lot. That's it though- it's probably an incompatibility somewhere else- not the AGP bus.

Well, I'm still trying to figure it out.

My "other" theory is the monitor - I have an older, PB 1411 (of which there are no current drivers, I've been using the driver for the PB 8510SV, as recommended by PB), and once had a problem with the frequency of the monitor and my old card - it had some similar problems. That got fixed through updated drivers, and flashing the card bios.

Also, some clarification on the problem - while DOS's screens "overrun" to the right and bottom, Window's screens are a) on every other line and b) appear to "loopback" vertically - a window, starting at the top, overflows off the bottom, and in every alternate line from the top, is picked up again.

So, while I try to get my hands on a recent monitor to test it out, I'm wondering if something changed in monitors / video cards' evolution to make a 5 year old monitor incompatible. (btw, I've tried all sorts of monitor drivers, and have no problem with my current card and the "generic" drivers).

Thanks for your responses to far.
