I've out grown my current setup at work. Currently running Intel i7 2.6GHz, 12 GB Ram, 64 Bit, with 3 additional dual core render farm (servers) setup on 3ds Max Design 2011 with Vray at work. I'm doing more and more short product demonstrations/animations and would like suggestions on how I can upgrade a render farm at minimal cost. These are primarily produced for youtube.com demonstrations and I'm rendering them at 720P but suffering from the long render times (1-2 days for a 4 minute product animation). We're not planning to become an animation studio but would like to cut down the render times in half.

Should I get another quad core computer on the server to help the farm? Implement a distributed rendering system using all of the PC's at work? Thanks for the suggestions.
