OK, I ordered a pretty fast PC from Amazon, kind of a no-name gaming PC but it had great specs, i7 3930 Six Core at 3.2 ghz.
Installed a Nvidia GTX 670, did the supported cards text file hack, and Premiere Pro 5.5 on it, along with Quicktime Pro, and fonts I needed. I also installed a nifty program called X-Mouse which allowed me to customize my logitech scrolling mouse to use Premiere Pro as I also using USB Overdrive on my Mac - indispensable software.
Got a KVM so I could use my 2 large displays currently hooked up to my Mac on the PC without totally disabling my Mac Pro 2008 8 core - it is my workhorse and I use it all the time.
Finally got the PC somewhat functional on with Premiere Pro and even got it working with projects and media via a fast network connection. It seemed like butter vs my old Mac Pro. My lack of being a Windows power user I'm sure was responsible for my ultimate failure at getting my Windows system, but there could be hardware issues with this particular PC as well. Ultimately it was a total pain to share projects and media that resided on my Mac. Using Premiere Pro on the PC was identical in many ways to the Mac, just faster.
However the PC started going downhill pretty much as I got it working. It wouldn't properly reboot, always spinning in the 'Shutting Down' screen. I had to hard restart it all the time.
Then things started to go south, probably due to system corruption from having to hard reset it. I installed a fresh OS on the other internal drive in hopes it would fix the problems, a whole new set of software to get Premiere Pro working well. Again, shutdown hangs, without any diagnostics other than windows coming up at the hard restart saying there was a problem with the previous shutdown, and wiping out a lot of stuff each time. Then in hopes of curing the ills, a reformat of the drives, reinstallation of Windows 7 Pro, and then the ability to actually install the OS. 2 reformatted drives that cannot b installed with OS. Epic failure. The replacement is on the way.
But this being said, the amount of time in order to make this environment 'cross platform' as well as the indiocyncracies of Windows (to me, I'm not bashing Windows - it seems to be a fine OS!) makes me rethinking the PC for Premiere Pro switch.
I realize the current Mac Pros are basically obsolete, however, MY Mac Pro really is, it's from 2008 and not the fastest model from that era (2.8ghz 8 core, non threading Xeon.)
Investigating "new" Mac Pros, I can get a 6 Core 3.3 ghz threading Mac Pro plus 32GB of RAM for about $3,500. I can get a 12 Core 3.09 ghz for $6,700 and a refurb 2.93ghz with 32GB for about $5,700. The Windows PC with everything I need is in the $4K range. I don't need any new peripherals to make it a direct replacement for my current Mac Pro, all PCI, peripherals will just work. I'm familiar with the OS, and all my apps and plugins will work, no KVM necessary, no cross platform issues. Just not as cost effective as the PC and perhaps slower.
Disregarding the cost, my time is valuable and I probably spend a good 3 solid days getting something non functional to work. There will be continual inefficiencies because I'm not a Windows shop, and I don't foresee this.
Will any 'new' Mac Pro, regardless of the cost, get me to the speed using Premiere Pro of this 6 core 3.2ghz i7 3930K? If I get the answer that the Mac 12 core will get me there, it may be a viable option. If the 6 core will get me 80% there, it might be the 'best buy' option.
Thanks for any advice, really!
