You're wrong Headfoot. I've talked with a person from ASUS and he told me that the video card that I've bought - a Radeon HD 7790 - 2GB doesn't have OpenCL support because they didn't implement it. GPU-z didn't show any Opencl support either. AMD says that the Radeon HD 7000 series have OpenCL support, but the manufactureres don't always implement it. They also use footnotes in the product description where they list their cards have AMD App Acceleration or OpenCL support to confuse buyers. They don't explicitly say this card has Opencl support with the latest drivers, or this card has DirectCompute support, etc. Here's a quote from the SAPPHIRE HD 7970 3GB GDDR5 product page: "AMD App Acceleration is a set of technologies designed to improve video quality and enhance application performance. Full enablement of some features requires support for OpenCL, DirectCompute or DirectX Video Acceleration (DXVA)." This is a pretty confusing description in my opinion. The best way is to talk to the manufacturer and ask if the card has the capabilities you need. Topweasel, I posted because it may help other people.
