For the price of 1 high end CPU that cuts processing time a fraction, you can get 5 cpus.
How to build a render farm (I know render farms are a great option for 3d, I image its the same with video editing)
Get fast results and save money
Im looking to upgrade myself, and the AMD phenom 2 for under $200 is a great option for me. It may take a few seconds longer to process "whatever" but the extra few seconds arnt worth the extra cost. Also keep in mind, (Ive seen people do this alot) many time people spend a fortune on cpus and neglect the memory and motherboard and other hardware. If you create a weak link, the lil extra cpu power wont show. If I buy last years "best-cutting edge stuff", I get a bitching system at a fraction of the cost.
An i7 965 would = 15,608.00 (cinibench score representing CPU power) For the same cost of the i7, you can get 5 AMD Phenoms_2x4 940(over clocked) which would = 61,800 (Cinibench score)
Thats 4 times more processing power than the i7 at the same cost. Granted I havnt factored in the other parts required for a render farm, but still should come close to what one would spend for parts to build a high end workstation.
