Which CPUs would you use? Two Gainestown Xeon Quad Core 5500s.
What CPU is faster than that?
Twin CPU motherboard?
Decent case with quality 1KW power supply?
Cost?
Can it run MacOSX?
Does the Nvidia board have EFI?
SEXY?
Who wants a SEXY computer? Many of us want a machine which actually works. There is your misconception. The Mac Pro is actually a machine for people who use it for professional or enthusiast purposes. It renders video and audio faster than PCs and it does it in industry leading software products (Apple Shake, Apple Color, Apple Final Cut Pro etc).
Ok some of us run OSX to actually get some work done. I can think of many things more fun than messing with icons and menus on a computer screen.
I'm not coming down on you but unless you do very intensive tasks on that machine you probably overpaid and are guilty of what you accused Mac Pro buyers of - a Macbook would do you well enough - it has a dedicated GPU
and plenty of RAM and a CPU which is almost as fast.
What do you do with it? Do you just run Office Apps fast? If you ran processor intensive tasks you'd realise how SLOW that is compared to a Mac Pro. 2.93 GHz 8 core Xeon vs a 2.4 GHz dual Core non-xeon without onboard memory controller, slower bus and less cache.
You like it primarily because it looks sexy?
Sheesh dude.. It was an opinion. No need to rip another person's opinion to shreds!
I said the Mac
BOOK Pro (the Notebook) was sexy.. and yes, why would I choose an ugly and cumbersome Dell or HP when the MacBook Pro outperforms them AND is more compact and looks better whilst doing so?
A large part of Apple's marketing relies on the design of their products.
Right.. as for the Mac Pro.
First and foremost, the majority of Mac Pro users are graphics designers.
The primary critera for a powerful graphics rig are GPU, CPU and RAM.
Secondly, the CPU, RAM and Motherboard components used in a Mac Pro are very closely-related to PC Server Hardware. You could build a desktop PC, using a server motherboard with multiple sockets, or even a specialized desktop board with multiple sockets (which do exist).
You asked "

What CPU is faster than that?"
The older Xeon is based on the Core2 Microarchitecture, which includes the Core 2 Duo and Core 2 Quad desktop CPUs. A 3.0GHz Core 2 Quad will give very similar results to your Xeon 5500, for a much better price. If you're talking about the brand-new Mac Pro with Nehalem architecture, it's the same architecture as a Core i7 CPU. PC hardware. I could use a brand-new Intel Core i7 CPU. Similar power to a 5500, at less cost. And if you do want that power, buy a Nehalem Xeon 5500 CPU or 2.
You asked "
Twin CPU motherboard?"
I could easily get something like an INTEL Desktop Board D5400XS. That has Dual CPU Sockets. If I wanted more, I could use a plethora of available desktop/server motherboards.
I could buy a couple of Xeons and slap them into that board or similar boards.
You asked "
Decent case with quality 1KW power supply?"
The availablility of PC cases far exceeds the word-limit of posts on this BB.
Almost every PC accessory manufacturer makes cases, including the component manufacturers like Gigabyte and ASUS.
As for a powersupply, the ThermalTake ToughPower series are the entry-level within the "decent PSU" range. You could spend big money on better brands, but this should give you an idea:
ThermalTake 1000W PSU
ThermalTake 1200W PSU
You asked "
Cost?"
Certainly less than a range-topping Mac Pro with all the options.
You asked "
Can it run MacOSX?"
Technically, yes. Legally, no.
So what? There's Windows, Linux, BSD etc etc...
I'd not pay R35k for something, purely because it can run MacOS.
You asked "
Does the Nvidia board have EFI?"
Do you know who originally invented EFI?
Intel did. Due to the extreme amount of different configurations available in the PC world.. it does take time to release new standards. But it's on it's way.
However, neither EFI nor BIOS really matter once the OS has loaded.
Something you didn't ask about, though, is Graphics Cards.
A
$2499 Mac Pro with a measly 3GB of RAM.. only includes an NVIDIA GeForce GT 120 512MB. That is hardly cutting-edge. My 10-month old GTX260 will destroy that, and you can still buy those for less than what it costs to upgrade to an ATI 4870 in a Mac Pro.
I attend the odd gaming LAN every now and then. One of our mates has a Mac Pro and his machine is out-performed, in games, by those of us with Core 2 Duos / Core 2 Quads with decent graphics cards.
Bottom-Line..
If money is no object, you can get much more powerful PC-kit.
But if money does matter, which I think it does to most of us, then you can save yourself a decent amount and still have Mac Pro performance in a PC.
