So it's not uncommon to go into a thread and hear terms such as "apple tax" and all. Well I just specked out a PC equivalent to a mac pro, and contrary to what many people in the PC community who think you can score this for half the price as a MP, both computers come out to within $200 dollars of each other (guess which is cheaper) PC: (these are the aspects of the PC to show the similarity to the MP) ASUS DSEB-D16 Server board 2 * Socket LGA771 Quad-Core Intel® Xeon® 5440 Series 12MB cache 1333 FSB (MP is 1600 FSB) Intel® 5400 Memory Controller Hub (MCH) Intel® 6321ESB I/O Controller Hub (ICH) Total Slots: 16 (4-channel) Capacity: Maximum up to 64 GB Memory Type: Fully-Buffered DIMM DDR2 533/667/800 Reg. ECC Total PCI/PCI-X/PCI-E Slots: 4 Slot Location 1: 1 * PCI-E x16 Gen2 Slot Location 2: 1 * PCI-E x8 slot (x8 link) Slot Location 3: 1 * PCI-E x16 Gen2 Additional Slot 1: 1 * SO-DIMM socket for optional ASMB3-SOL Additional Slot 2: 1 * PCI-X 100/133MHz (for LSI 8300XLP ZCR Card) Six SATA (RAID) slots, 1xEIDE, and 8 SAS. Quad teamable gigabit LAN. Components: 1. ASUS DSEB-D16 Server board: $640.00 2. CPU's: 2x Intel XEON 5440's, 2.83 GHz, $720/each 3. Case: Silverstone full-tower case, $270.00 w/hot swappable SATA Bays x4 4. RAM: 4x2GB sticks of fully-buffered 800Mhz RAM: $400.00 5. HDD: 2x500GB WD RE2 drives: $240.00 6. Video: ASUS GeForce 8800GT 512MB: $220.00 7. DVD: ASUS 20X SATA DVD-RW +/- DL with litescribe: $30.00 8. Firewire: 2x800Mbit, 2x400Mbit firewire card (case has header for front panel accessability) $35.00 9. Audio: Turtle Beach Montego 5.1 Channel sound card with dual optical out: $40.00 10. PSU: Zalman ZM1000-HP 1 KW Power Supply: $300 11. OS: Windows Vista Ultimate 64-bit single license OEM: $170 OR Linux (-$170) 12. Other: Logitech Keyboard + Mouse: $30 (Components from Newegg) Total: $3645 (Linux/Pre-existing Windows license) OR $3815 (Windows Ultimate OEM) Mac Pro (we all know what the MP has, so I'm not going to spell everything out) Quad-Core Intel® Xeon® 5462 Series at 2.80 GHz, 12MB cache 1600 FSB Components 1. Server board 2. CPU's: 2x Intel XEON 5462's, 2.80 GHz 3. Case: MP Aluminum case 4. RAM: 4x2GB sticks of fully-buffered 800Mhz RAM: $400.00 (OWC) 5. HDD: 2x500GB WD RE2 drives: $240.00 (OWC) 6. Video: nVidia GeForce 8800GT 512MB (+$200 CTO) 7. DVD: 16X SATA DVD-RW +/- DL 8. Firewire: 2x800Mbit, 2x400Mbit 9. Audio: 5.1 Channel with dual optical out 10. PSU: 1 KW Power Supply 11. OS: Mac OSX Leopard 12. Other: Apple Wired Keyboard + Mouse 13. Other: Bluetooth 2.0 1-3,7-13 = Base Mac Pro: $2799 Total: $3640 (keep in mind, you're keeping the original 320GB HDD and 2GB Apple ram, so you will have 10 GB ram and an extra 320 GB HDD compared to the PC with 8GB and 2 x 500 GB). Total: $3640 So a PC equivalent to a Mac Pro cannot be purchased for a cheaper price, but will cost you an additional $175 (or 5$ if you choose Linux or have an extra license of Windows). And not only that, you have to purchase all of these parts and build the computer yourself. So unless you have "mad skillz", your home built PC will be lacking in quality compared to the Mac Pro. The only differences between the PC and Mac Pro are the FSB (1333 vs 1600), having those differences was as close as I could get. So getting a processor for the PC with the higher FSB would put the price of the PC even further beyond the price of a Mac Pro. The MP also has an extra 2 GB ram and 320GB HDD (from the base config), giving it even more of a boost. Mac Pro advantages: Pre built, better build quality, OSX and Windows, CHEAPER. PC Advantages: Better expandability (esp GPU) So the next time you use the phrase apple tax, remember that it only refers to the additional components that can be purchased 3rd party (such as ram and HDD's), which any wise consumer would do.
