I know this is crazy, but I've seen 4xx and 5xx NVIDIA users having problems with Dolphin being much slower than it should be. Is it possible that BufferStorage isn't being detected properly on those video cards?
Disable the Vertex Streaming Hack in the last version that has it. If performance is absolutely identical, then the problem is probably something to do with BufferStorage not being detected or used.
