It depends on how FinalCut and Motion are coded to use the hardware in the 5770 and 5870. The 5870 has 1600 shader units (5770 has 800) and a 256bit memory interface (5770 has 128bit). Memory throughput to 5870 is double that of 5770.
Also, if FinalCut and Motion use OpenCL (compute language which uses the GPU to perform many parallel operations quickly that the CPUs would choke on) the 5870 would be the best choice. The 5870 has almost twice the compute power compared to the 5770.
Time is money. $200 is a small upgrade cost if you're doing production video work at $250/hr or more.

With a couple more cores, a greater frame buffer, and an increased clock speed, you will see it crunch frames faster and provide decreased render and encoding times. The amount of decrease depends directly on the size and complexity of your projects. If you are using more than two monitors, I would highly recommend considering two 5770 but the 5870 has done a lot for me in a generation gap upgrade. If you have a 5770, it is not worth the upgrade unless you use the computer for daily rendering.
