Pardon my ignorance, but Isn’t bootcamp made for that ?
I think that one 980ti is already faster than a radeon 580, let alone 2 of them.
A windows OEM licence (with a hard drive for instance) is about $100 i think, so the math would say stick with your cards.
As whether Prorender is worth it… it’s good enough to play around, but it should be improved in R20. It had various improvements from the side of AMD (including a denoiser) + whatever Maxon worked on their side (Disney PBR shader? let’s hope…). So this might become a decent solution :
ProRender improvements :
- Improved heterogeneous volume
‒ Efficient sampling, less memory
- Metal support on MacOs
‒ Requires MacOs High Sierra (10.13.3)
- Nested Dielectrics
- More AOVs
‒ Per BRDF AOVs (diffuse, reflect, refract, volume)
- Color LUTs
- Color correction using .cube file
- Procedural UVs (Decal projection, triplanar)
- Easier to use Uber Material (Closer to Disney)
- Performance improvements
- Real time denoiser
