Rumour has it that Nvidia is set to release their Kepler-based GTX 680 on March 22. With a reported 1536 CUDA cores, and retailing around $560 USD, this card may quickly become the low-cost GPU of choice - certainly at Parallax Innovations HQ. We’ve been happy with the cost-effectiveness and performance of the GTX 580 GPU, which we use with our GPU CT conebeam reconstruction software , but at a comparatively small 512 cores we see a hardware upgrade in our not-so-distant future.
