It looks like this benchmark better rate 6xx series than previous ones, and it gives poor results with MAXWELL GPUs.

I’d be curious to discover why I’ve seen render times with this same Gfx card and operating system but notably different rendering times. I had no other processes running to slow things down.

Identical system to that which I previously benchmarked on my OS X partition (post # 13).

Will perform on Linux at some stage as well
Yes I am. 2.71 released 6-25 according to the splash screen.

Looks like a GTX 750Ti is a good choice for my personal use, compared to this.

Though personally I don’t feel that Blender is necessarily that stable after a OC render. You can have to restart it to get normal render times back as they can go to half.

Very true, something definitely changed, Fermi is much slower now. With the Octane benchmark my 2 460s usually almost equal a 680, very strange. Maybe a driver change has boosted Kepler’s performance. I think it’s time to start looking for an upgrade.
