The example that you gave are one and the same but if you just saay an adapter card, then it could mean lots of different types card.
As for the directX thing, Some of the newer graphic cards have directx chips built-in (I think). I don't think rage pro meet that requirement.
I was under the impression that a video card, graphics card, and video adapter card were all the same thing, but now I think I'm wrong. On my PC, whenever I'd run software to detect what video card I had, it would say this - "ATI 3D Rage Pro AGP". It's been called a video card or a graphics card by different software I use and when listed under my device manager, it's called an adapter card. That's why I thought those were all the same thing.
However, I recently purchased software that says I don't have a video card. I checked the requirements and it said I needed a video card that was directx 9.0 compatible and could handle up to 32-bit color and a resolution of 1024x768. As far as I've been able to tell, that 3D Rage Pro meets all those requirements, but I could be wrong.
Can someone clear this up for me?
