I went to school for EE but that's beside the point. Xeon or non Xeon is sort of moot unless you're working for Columbia Tri-Star and even then, I've seen some iMacs at Bravo, 5th floor NBC building. Burbank, where they did audio and vide for bumpers using Aja/Kona set ups via chassis. The old metal case, still timeless like "The Beatles", (O.T. "Abby Road" still #1for most sold record in billboards top 200 of all time.
FPU is needed for audio. The higher the FPU the faster and more plugins you can use. Yeah sure. Some new chips are coming at 3.5,3.0 and lower as you get more cores while there are 4.0 Ghz, turbo 4.4 and unlocked for over clocking. CPU life3-5 years but by then, those type of people look at Intels road map to make sure they have (example), 3.0 USB, Thunderbolt and most important same pin size on the road map so they can swap the CPU.
Higher FPU means more plug ins. I'm using a Apollo quad that I paid the amount a duo cost so that's a huge help. Plus there are rumors of added DSP CARDS IN THE WORKS FOR MORE POWER.
So why Xeon or lower clock speeds for the more Cores? Because, due to the design, it can't take more than 135 watts. Give me the metal case and you would be getting faster Xeon's and like mentioned previously, faster, more plug ins and no chassis are need as you had 3-4 slots (PCIe) and could go faster with more wattage.
I built a Hackintosh once but it was for kicks but seeing how the new Mac pros are more 4 video, they tried but haven't gotten the GPU to work for audio, today a hack can be built and for free you download an EFI program, so you can update and since it's a PC, you can probably get two 8 core 4.0, over clock to 4.5-5.0 on air, speculation, but at least 4.5. Plus ever since the 12 core was on par with the Neleham 2.93 keeping up I was hoping to really be blown away. But limited? Wow. Those that say wait for then rev 2 must be correct, I would love to find one. Please. For kicks see if you can find them. When the 12 core came out they were $1900. Now they are much more after seeing the old 12 core results,and you can always throw in a USB 3 and thunder bolt card. But am sure someone will build a stable hack as it has no idea it's a PC as soon as the software boots. And now that MS has but one OS, I'm betting they will get a lot more,products moving as everyone will work,on one OS instead of dealing with nearly a dozen os's and the reason for the letter is because Apple needs to brink back the metal case. Make the barrel for Pro-Sumers and the metal for xeons or whatever you want to place in there, for the pros. Keeping our desktop,free of clutter.
I see apple as taking a step back. And with 4k tvs being at $1500 for a great 40", where talking monitor heaven.
The metal case will keep you from chassis, I read about TB glitches all the time. And you get 4'hard drive spaces to boot. For the noob. I don't think MS shows the code in booting anymore. But Apple foes the same thing. Just programmed to hide it. Boot in verbose mode )apple) and you'll see. While for the PC user should Microsoft ps new OS show the boot up code. You can change it in the bios screen to what ever image you want. I've been using macs for a long time now so have no idea.
Don't get me wring, more cores are great. But more cores at higher clock speeds are even better. Imagine a 6 core Xeon 4.0 running at 4.5 at full load or even prosumer can with i7 8 cores with quick synch!?, support.
"As Audio and video really need high Ghrtz and intel released a 4.0-4.4 and apple will never have the ability to use in its current Mac Pro form. Only in the ageless steel version."
Huh? Why do you think they'd never be able to use this in the current Mac Pro?
"Or the Mac PPC? Nope. Only the design of the metal showed the world it was a timeless piece of art and will never die."
You do know PPCs came with the same case design right?
Ugh, what am I doing. I don't even know why I'm wasting my time with this.
