Hardware problems

Hi Guys,

My blender is slow and having very quick a memory problem,
I want to know if it is my hardware:

Intel I5 2500 sandybridge
16 Gb memory
1Tb HD
Nvida Gefortce GTX 960 2Gb

In Preference I put on:
Compute device, CUDA Geforce GTX 960
open subdiv= GLSL compute
And in render:
Device GPU compute

Is it normal with this config that I can’t dot to much ?

Could you be more specific? Slow while doing what? What kind of scenes (polycount etc.)?

And under what conditions do the memory problems occur?
If you’re talking about rendering, it’s not at all surprising: 2GB VRAM is more or less the bare minimum these days…
