Kepler, are they worth it?

I'm looking at the specs of a nvidia kepler card and wondering if they are worth the money and would they be beneficial to 3d modeling if you use gpu rendering like luxrender or octane!

Has anyone got one and do you notice the difference?

I suppose it does not really matter as I bought a nvidia quadro k5000 so I'll have to find out for myself if the any performance upgrades are worth it, just need to install it first!
