We have an application that uses OpenGL, and historically it has run lousy on ATI cards, although results have been different depending on card/driver combo. We're trying to put together a test machine on a very low budget, where we can swap in different ATI cards and test them. I was wondering if anyone has a good knowledge of the different ATI series, and what cards I should buy to get a broad swath of the different implementations. Is it enough to buy one card in the Radeon HD series, one card in the Radeon X series, and one card in the FireGL series? And will these be able to cover the "mobility" implementations in laptops (we don't want to have to buy a laptop because you can't really swap cards there)? Also, are there any articles you can point me to that talk about this? I've perused ATI's site but haven't really found much intended for hardware testers.
As an addendum to this question, we're not as interested in benchmarking/speed as in just getting our app to work right with all possible cards. According to user feedback, with some cards, our app will just crash, and in others textures will not be rendered properly. On some the picking mechanism doesn't work, etc. So we're not really looking for an OpenGL testing/benchmarking software. Our app is the test software. We want to test our app against different hardware. So how many cards do we need to get, and which ones, to kind of "comb the area" of the primary hardware categories?
Answer
FurMark is a good OpenGL testing tool.
You could also keep GPU-Z handy.
FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that's why FurMark is also a perfect stability and stress test tool (also called GPU burner) for the graphics card.
The benchmark offers several options allowing the user to tweak the rendering:
fullscreen / windowed mode, MSAA selection, window size, duration.
benchmark requires OpenGL 2.0 compliant graphics cards -- works with AMD/ATI Radeon 9600 (and
higher)

Update: Reading your question again, I have a feeling you should actually use your Application itself for this testing. You could use GPU-Z for recording the Driver, BIOS and Card details while testing.
Is there some specific sequence in your App that will execute most of the rendering cases?
It might be required to 'tweak' your App a bit to adjust to all driver+card idiosyncrasies.
Update2: You will need some help from people experienced with the range of cards from ATI to get generic. Your target should be to enumerate the set of graphics operations that your App makes on the graphics cards.
This will be your customized test across the cards you choose to be 'compatible' with.
The ATI experts should give you guidance on the list of card+driver combination to run these custom test against. As a result of such testing, you will,
- identify the card+driver set that your App will be compatible with
- identify the minimal operations that you need to fix in your App to get a
decent set in point 1.
- identify the minimal operations that you need to fix in your App to get a
