i do alot of vid editing and was wondering if i upgrade to the new flagship would it improve the time it would take for it to compress the films
If the video program you're using can use more than 4 cores (8 threads), then yes, you should see a 50% improvement theoretically (50% more cores / threads). Real-world will depend on how well the program scales to multiple cores / processors.
I'm willing to test this out providing someone will give me a 980 On a Q9650 at 4GHz rendering times for my test clip were 13:47 with Premiere Elements 3 (which doesn't recognise HT cores. On a i7 920 it takes 05:12 with Premiere Elements 8 which does use the HT cores. The same clip used to take about 62 minutes on a Pentium 4 2.5GHz.
I thought encoding uses the GPU these day in age, as they are much more powerful in doing such a task than a CPU. http://www.nvidia.com/object/builtforadobepros.html
