You are actually NOT going to get optimum performance on a single machine, despite dual processing and dual core and all that.
What I suggest is spend your budget, buy a bunch of older PC's, and setup your own rendering farm
Hello, I'm very interested in making 3d photorealism of the highest quality. i intend to make Din A-3 size at 300 dpi, and i'd like to know which hardware is the best we can afford to make this renders as quick as possible with lightwave. It's very important for us to get to make a render within 1 hour or so. could anyone help me??? please. thanks
