I'm sorry. I grimace every time I see someone suggest that anyone buy anything less than a card that ends in -80 for rendering. For a few dollars more, you can get a real powerhouse rather than something the manufacturer crippled to sell at a lower price point. Sure, get a -70 if you like to pay hundreds of dollars for less than optimum performance, but if you are going to spend that kind of money--you really want something that ends in -80, the more CUDA cores the better. Go look at the benchmarks on the Daz forums. I can verify what others have said about that series of cards, especially when coupled with another card.
