Guys, I have purchased a camcorder, the jvc gz-ex210, and saving a 2h46m video in the best quality wastes 28 GB. Using sony Vegas pro 11.0 in a q9450 with 3 GB DDR2, Windows 7-32 takes over 18 hours to render that video, after inserting a few audios and a single image.

Currently i am thinking of buying a new PC with 8 GB RAM (at least for now). Still undecided about the CPU, between i5 4460 and i7 4770. I tried searching for benchmarks but have not found anything substantial.

Can you please help me on this? How much improvement I can expect if the i7 is chosen over the i5? Is there an estimate somewhere?

For example, let's say the same task would take 6 hours using the i5. How long will it take on i7? I need to know if the difference $ is worth paying for.

For heavily threaded stuff, the i7 is usually 30-40% faster than the i5. Or if you insist on having that expressed in terms of time, a 4h multi-threaded encode on the i5 should take about 2.5-3h on the i7.

This forum discussion seems to imply the GPU can also be involved in the amount of time involved for video rendering, at least with Vegas Pro 12....;

No certainty these results could be applicable to you, as it might definitely depend on which (if any) GPU you have/use...
