I wish I could find the thread in this regard, but I do recall Oshyan or Jo mentioning that the benchmark file is obsolete due to the upgrades since its release on 3D Speed Machine, Will there be a follow up file for marking the newest version 2.5 in the future ?

I will be publishing a new benchmark scene some time in early 2013.
