4GB for doing GPU rendering is crap. I know because I have two 4GB GTX cards. You'll run out of texture memory and one of three things will happen: The render will crash, the render will slow down to a crawl because of memory swopouts or Poser will crash. One clothed figure with a furnished room prop is enough to go over 4 Gig. When using multiple figures I Use the same textures for hair/inside the mouth/ eyes to save memory.

If you have enough RAM (minimum would be 64GB) you can uncheck "Separate Process" and you won't get that Buffer Overrun/Out of memory error thing from Cycles/CUDA. The only issue is, you won't be able to use more than one video card if one of them would normally run out of video memory with the scene. But by doing this, you can use a 970 or whatever and it will simply spill into your system ram. The big drawback is that it will eat that RAM like a starving lion... I just upgraded my comp (switched out mobo/CPU/RAM) and went from 32 GB to 64 just because rendering using system ram would kill my resources and I couldn't do anything else or my comp would crash. Now with this 64GB, the scenes that were eating my ram up are barely even hitting 40% ram usage, so I can do other things like play games or do Photoshop/Vegas editing and not worry about system resources and stability.

The sad thing is, upgrading those three components was cheaper than finding a 1070/1080 to use as a slave render card so I could finally replace my 970.
