Quad macintel woodcrest vs quad PC woodcrest:
It was driving me crazy, so I had to do it, I newegged a parts list which as far as I can tell comes close to being a mac pro, and costs about the same as what I would pay with the student discount, so here goes:
(prices on newegg)
Lian Li PC-201B Black Case - $269.99
X7DA8-O Dual Socket 771 Intel 5000X Motherboard - $549.99
ASUS EN7600GT SILENT Video Card - $209.99
Antec Phantom 500 Power Supply - $159.99
2 X Intel Xeon 5160 Woodcrest - $1,833.98
4 X Crucial 1GB DDR2 FB-DIMM DDR2 667 (PC2 5300) - $777.96
2 X Seagate Barracuda 7200.10 500GB Hard Drive - $579.98
Logitech Ultra X Wired Standard Keyboard - $21.99
Logitech MX518 PS/2 Optical Mouse - $39.99
Pioneer 16X DVD±R DVD Burner - $31.99
TOTAL: $4,405
(excludes OS, support, monitor, etc)
The MAC for comparison:
power mac case
mac pro motherbard (5000x chipset as far as I can tell)
Nvidia 7300gt(slower than the pc version)
apple PSU
2 X 3GhZ woodcrest
4GB Mystery RAM
2 X 500Gb Mystery HD
Apple Keyboard
Apple MightyMouse
"Superdrive" DVD burner
TOTAL: 4,549 (with academic discount, includes OS and support, no monitor)
I left out the OS hard drive, tried to pick the PC parts that would result in a quad woodcrest for the same price as the mac(hoping that the pc I specced out would be the obvious better deal for the money, but I was surprised), but there are more variables here, like cooling devices, OS cost, etc. It still is really surprising, the mac pro looks like a good deal compared to this thing I picked out, with the added convenience of knowing for sure that it will already work for doing the audio stuff(on the PC side quad woodcrest audio workstations are still very experimental type things from what the forums have been saying) (though there are problems with things like protools on a mac at the moment as well). You can put multiple video cards in the mac pro but there is only 1 pcie x16 slot in the pc board, but for the money you can put a nicer video card in the pc(which I did, with the fanless 7600gt). It would be neat to have these side by side, to compare their noise, I tried to pick out parts that would keep the pc close to the mac in noise but I have know way of knowing for sure. (wish tomshardware would get this stuff and write an article for me, except with better comparisons)
Also the macs come with firewire, some sort of fancy heat spreaders on the RAM, a warranty, and you might could argue a better motherboard, despite it not supporting as many video cards. Usually I can make a system that easily has better parts than mac for the same money, but this one is quite a different situation. If I were rich enough I might consider getting one.
