Sorry for the late reply, trail exams and finishing assignments.
The 590 is monstrously fast compared to other Nvidia graphics cards iv had (280, 480,580)
Simple scene that minutes to load, and with my latest tutorials (with instancing) i can render 4K renders of lush environments within an hour or two.
Although i have like 1 Mb left of Vram
That is crazy! They are not selling them 590s anymore also!
I just upgraded to 2x gt580, amazing rendertimes.
I am still able to use my workstation for photoshop or Solidworks, using the integraded HD4000 in the 3770K. I can even render with Octane and Keyshot (cpu-based) at the same time, on the same pc, with barely losing performance!
How hot do the cards get? I had to put my pc (thermaltake tsunami) almost outside (near the window), due to poor airflow, and put 2 fans directly at the 580s.
Temperatures dropped from 95C to 75C!
