Component maker Sapphire has officially launched the Mac Edition of its Radeon HD 7950 video card. The add-on includes 3GB of GDDR5 memory, and is said to boost game framerates by as much as 200 percent or more, and general benchmark performance by about 30 percent. Graphics-heavy benchmarks are claimed to run up to 300 percent faster than possible with the NVIDIA GeForce 8800GT.
