I know this seems like a dumb question but I am a bit confused. About a month ago, I checked out the Wiki page (
here) regarding the comparison of GPU hardware. I went out, bought me a cheap, but decent card and through it in a computer that I have.
After, installing various drivers and ATI/AMD SDKs, I never could get the thing to work. Then, I think I realized the problem. It appears that just because you buy a GPU with one of the listed ATI processors, it doesn't mean that the card is OpenCL compatible. WTF!
What should I be looking for in a graphics card? I know that most of the Sapphire brands seem to be guaranteed to work, but what are the specific specs on a card that make in compatible with the OpenCL drivers?
