USWC - who has it and does it work?

[4keatimj]

This might sound slightly noobie, but does USWC work on modern cards? Nobody seems to say anything about it in releases and tests/benchmarks, and that leads me to the other half of my question... who has it enabled on their machine? It works on my machine (see sig), and easily get heaps more FPS in games (OK, so their old games, but still... ), but, like I said, I don't hear anything about whether its enabled or not in tests and benchmarks... so what about you guys and girls?
