Get it soon as you can....it was a bit of a stretch for me, too, but very glad I got it.
1. *Faster and much less expensive than a Titan card with no extra heat.
2. I didn't have to upgrade my main board or power supply.
3. much better workflow
4. animated materials.
Highly recommend it.
BTW, is the final version going to be 120 Euros? All the others are 149~199 Euros.
*at least vs my GTX580 (see Tom's)...i.e. OR4B renders 3.6x faster than StandAlone/Plugin 1.19.
Getting OR4B AND replacing the 580 with Titan(s) would be best, but
out of my price range, and don't need that kind of speed.
