NVidia 6000 series and better support it for sure. And I know anything less 
than 5000 series doesn't support FBO.
I didn't remember that 5000 series doesn't support npot textures though.
Looking at the FBO extension spec, it seems to also work with rectangle 
textures (which are supported by 5000 cards), so I'll try to add support for 
them to GLRenderTarget.
