Billbartuska, I'm not sure what you mean by dual booting two OS's. (Windows 7 and Linux, for instance?) With modern machines, nobody really dual-boots anymore. If they truly need the availability of two different operating systems, then they run a hypervisor and open a Virtual Machine for each OS they want to have available. There is a very minor performance penalty to pay compared to a dedicated single-OS machine, but with modern hardware it truly is negligible against the benefits of infinite flexibility.
To answer the OP's question, any of those processors will work well for the task at hand. The E5 series is typically more utilized in servers, so if you build around this processor you might need to get a server-grade motherboard (such as from SuperMicro) to work well with it. These processors might also use ECC RAM; you'll need to check on this. If I recall, the E5 series, unlike the core i5/i7, don't have integrated graphics features, although if you're doing video editing you're going to have your own video card anyway, so it won't factor into your equation.
The core i5 or i7 tends to be used more often in desktop machines. I would personally go with one of these. It's going to be easier to find a compatible motherboard. The difference between the i5 and i7 is that the i7 supports hyper threading, so it can run more threads per core. For a server setup, where you might have hundreds or thousands of different machines making simultaneous requests that each spawn a new thread, this might make a difference. For a desktop machine for video editing, I highly doubt it will make a difference. You will need to look at the software you're planning on using for the editing to see just how well it can handle parallel processing. If you're software is single-threaded, you are unlikely to get any additional advantage to having more processor cores or hyper threading.
Any of these processors with at least 4 cores will be fully up to the task. I agree with the 16GB of RAM. For video editing, you will also need very copious storage space that can be quickly accessed. So at the very minimum, a good 4TB hard drive with a SATA 6Gb/s connection. If you're editing a lot of Blu-ray discs, you will need to investigate RAID to allow you to utilize a large amount of storage (more than what a single hard drive). You'll also need a good backup plan with an external hard drive.
I don't see how the choice of processors here will affect audio quality in the least. It won't make a bit of difference for editing. For playback, as long as the processor can keep up with the audio/video streams without interruption (and realistically any modern hardware can do this with very little CPU load), it shouldn't matter.
And for a video editing system, you'll need big displays and a comfortable keyboard/mouse interface, so it's unlikely to be embedded in your audio rack. Consequently, fan noise shouldn't matter. Now, if the system were to be a home theater PC that was effectively another component in the rack, then you would be considering a low-noise strategy (large fans, maybe active heat sinks or water cooling). But for a video editing system, it's likely to be in your office or wherever, so that's probably not a primary concern.
Put simply, the specific processor choice shouldn't matter tremendously. I feel the more important thing is to have the drive space, video card, software, and RAM to effectively deal with large-file video editing.
