Tesla k20

So I´ll get the chance to try out tesla k20 for few hours soon(about a week) and I was wondering if anyone would like to try some cycles renders for benchmarking.
I’m going to do the bmw test and post that but if anyone can assist me in getting some more complex tests it would be great.
My hope is to get some complex blend files, no need to be actual production stuff, to compare to gtx 580, 600 family and other gpu if possible. according to current info about the geforce titan the tesla k20 is the closest product avaialable to date so it could prove to be quite interesting.
Test will be done after the current rumored launch date of the titan but the test of k20 was planned as testing for future upgrade of my computer.
