Yes, this is a huge issue. In looking at benchmarks, the first thing I'd really need to do is eliminate all sources of extraneous and unwanted variability. Note that from a statistical standpoint, you do want variability, but in the dimensions that matter (and can accommodate it).

If I'm not running the same workload against each card, then I have no business making a comparison.

There's actually a more subtle criteria than just extensive. It needs to be extensive and in usable form.

Anand does a lot of testing, but I'm unsure of his methods and the data is in a useless format.

The notebookcheck guys have data that is in a very tractable form! I read a bunch of their reviews, and they all seem to have a reasonable approach.

To put it in perspective, if I had to work from [H] or AT, the article would have never been written. I simply have better things to do with my time than try and manually reformat data from a website into a spreadsheet.

My preference would be to work from Scott's data at TR, but he doesn't use 3DMark.
