I have reason to suspect a lot of us are wondering what are the
corresponding improvements in performance due to factors such as choice of
driver, OpenGL tweaks, registry hacks, etc. and a system specific analysis
with a reliable benchmark tool is the only way this can be achieved. One
where numbers can be generated and you could feel reasonably certain these
numbers were realistic. It hasn't been disproven that the benchmark tool
before us isn't one we can feel comfortable basing these numbers on. Albeit
the exercise is time consuming for any individual.
