Difference between AGP versions (4x, 8x,...etc)

I bought an AGP (8x) - compatible video card yesterday. I have two questions:

1. I know my motherboard back home is AGP-compatible, but I don't know if it's 4x or 8x.. is there a difference? will this video card work with any AGP motherboard

2. The video card is 256mb. Also how can I know my motherboard will support it? or will it readily work?

I'd appreciate your help.

Forgot to say that...

I bought my PC in mid 2003. Shouldn't the motherboard inherently be AGP 8x compatible?

Don't know if this might help.

Just knew that it's 4x :(

Seems you have a history on this one.

I see you have dozens(?) of posts about monitors and maybe cards but let me make this answer direct.

1. There is not a AGP card made that is 8X and does not work in a 4X slot.

2. That 1.5V is a misread of the document. No where does AGP slots "supply" 1.5V but it is true that the AGP card can request 1.5V. There is a subtle difference.

Yeah, I have had dozens..

..of threads on that, but finally, I've actually bought the stuff!

Thank you for your reply. I've gotten it even confirmed via nVidia's official site:


Now I wonder if it's a wise thing to go back to the store and get a 4x card? Are they available these days? Shouldn't they be cheaper?

That's unlikely. Here's why.

In reply to: Yeah, I have had dozens..

It makes no market sense to design a 4X only card. That is, your 8X (that works in the 4X slot) will likely be just hunkey dorey and if you found a 4X of the same stature (unlikely) it would also likely underperform your new card since it's from a bygone design day.

And again on the LCD. Yup, even a CRT can ghost. It's normal and drives some gamers and new owners nuts.

Thank you.. now I don't need to worry about my new vid card. It's always shocking to know that your just-bought thing won't work, you know.

As to the ghosting, I don't feel it in games and vidoes as much as I do when scrolling, but it seems I've got used to it a little bit.

What's driving me crazy now is the contrast issue. The upper portion of the screen is somewhat obviously darker. Whatever position I set the monitor to, it doesn't go away. It only becomes normal when I raise my head and look at that portion dead straight. If that's because of its 140-degree viewing angle, it sucks.

I wonder if DVI would affect the viewing angles? I don't mean widening them, but making display parts within them kind of more identical. I assume it's a pure mechanical thing, so I'm not sure.

DVI will not affect viewing angle.

In reply to: Re:.....

That's an easy one. Thanks for that.

You are noticing a display "quality" issue. Some are better than others in this respect but the price tends to go up.
