I have been following the GPU and OpenCL development for a while, and now want to get my feet wet to start development on OpenCL with appropriate GPU card. So, my first question is "how do I start ?". This leads to the following questions :
1. Is there any FAQ available handy for beginners ?
2. Any suggested GPU cards with good price-to-performance to start with ? R280X ? R290X ?
3. My primary working and development environment is Linux. Can I use the same GPU card to run OpenCL programs and use it as display card at the same time ?
4. Can I install more than one GPU card into my computer ? What's the co-relation between OpenCL and CrossFire ? How do I specify which GPU card to run the compiled OpenCL application ?
