In-case you didnt know Nvidia got there forums back up Nov. 1 (5+ months)
Someone did a driver comparison here -> Fall 2012 GPU and Driver Comparison Roundup
W1zzard should do a test but hopefully stick to one system setup vga rev. Going between system setups & vga revs is just odd. Like he states
Benchmark scores in other reviews are only comparable when this exact same configuration is used
Unless i'm missing something its clear you cant be consistent on each rev. Although i'm guessing scores from all revs are carried over to make the graph.
System Setup might change in a while within revisions but drivers change and depending on whats released/reviewed you always have obscurity with the past #/scores. If those scores are carried over from the time of review or re-run with noted rev.
AMD & Nvidia are always run on different revisions and with-in those revisions you'll always have a different drivers used on the product being reviewed ofcourse and those refered to in general.
