I'm a new user of Octane demo (standalone + C4d plugin) and I love (i mean, i loooove) this soft !!!

Unfortunatly, I work with a GTX 285 (Mac pro 2009) and i have lots of "freeze" when i'm playing with Octane.
Is there a way to solve this ? Or should i buy as soon as possible a new graphic card (probably the GTX 980)...?
