GPU benchmarks

I have a time of 2 minutes 1 second for the GTX TITAN which is slower than previous times. In 3.00.06 I had 1 minute 45 seconds. In 2.40.04 a time of 1 minute 37 seconds. Due to various driver and V-Ray updates Its impossible to come to a conclusion. Just to clarify I wondered if anyone else who has a TITAN could run a test on the latest 337.88 driver and V-Ray version 3.00.07.

Thanks,
