Not really true about the GPU on 8.4/Yosemite. Only a few GPUs are supported so far for "acceleration" on the Mac in 8.4. It's still not at the level of acceleration you see in other NLEs. Not using OpenCL or CUDA to do any heavy lifting. You would only notice anything with very specific tasks.
I also upgraded a 2009 Mac Pro 4,1 from 2 x Quad Core 2.6GHZ to 2 x Hex Core 2.93 GHZ. Best move I ever made. For less than 500 bucks, I got a machine that benches close to a trash can Mac Pro but way more flexible. Got to keep my PCIe cards (RAID, AJA Kona, PCIe SSD, Nvidia 680h. I did not go to dual 3.46 over concerns about power consumption at heavy CPU use. With all PCIe slots filled and a power hungry GPU it can approach the rated spec on the PSU. Did Apple ever sell a machine with dual 3.46 Hexcore Westmeres?

Just finishing a feature film, 100 hours transcoded to DNX115, 3 hours timeline (though I break it down in 40 minutes chunks when I edit), on Mac Pro 2x2.26 with the 8.3.1/10.8.5 combination, and a Nitris DX attached.
It's been rock solid, never skipped a beat. Half way through the edit, upgraded the processor in the Mac to a pair of 6 core 3.46Ghz and a beefy Radeon card and upped the memory to 48gig. It made it even smoother to use, very responsive. Shame MC can't use the extra GPU power - though I seem to understand that it does with 8.4/10.0.xPierre

conditions:
- no AMA

- hardware 'happy' (not interrupting)
Even then though, I get symptoms where I hit play, audio plays fine and
video skips and lags. Hit stop, then hit play again, and it's fine. Caching
of files seems to be what's happening to slow things down. Once the app has
'found' all the files in my sequence or viewer, then it catches up and
plays OK. So scrubbing quickly through a timeline is relatively annoying,
since it's a slow caching issue, and caching lots of files is bogging down
MC.
