I understand that if I get a new graphics card that's got a nice big GPU on it then I understand that I'll get faster previews and but not faster rendering.

I'm currently getting black screens with OpenGL and my slower motherboard based graphics so I've turned off OpenGL and am using the Software option.

Will the new GPU make any improvements with this option turned on?

Also the Daz3d site says that all I need is a "**OpenGL compatible graphics card"
**
I'm curious to know which version of OpenGL that is? 1? 2? 3? Does it matter?
