...

Secondly, another difference favoring Bitcoin mining on AMD GPUs instead of Nvidia's is that the mining algorithm is based on SHA-256, which makes heavy use of the 32-bit integer right rotate operation. ...

Does ATI cards also got an edge with SHA-512 or would switching to 256's big brother give NVIDIA peeps a better chance at blockfinding?
