But fact is they are. Processor wise I agree with you, but for the amount of money that a base Mac Pro costs you'll get similar pcs with ATI 5870 gfx chips, 6-8 gb ram, 1-2 1 tb hds etc... adding these to a base Mac Pro quickly brings its price above 3000 bucks. And if you go from a Xeon to an i7 (which, in a single processor configuration, makes little to no difference) you can get such a system with the above addons for around 1500 €, where the Mac Pro starts at 2300 € and will reach 3000 € with these extras.
No, they are not. I'm talking WORKSTATIONs here, not 'desktops'. People forget this is a workstation class computer, and hence gets a price like one. Always has been the case, always will be. Thats why people call for a xMac which uses desktop components (i7 instead of Xeon), etc which would knock £500 off the price, maybe more.
My Mac Pro: £2145
Go and custom config a Dell workstation and you get £2045 give or take.
Go and custom config a HP workstation and you get around £1700.
Moving on... Top end octo 2.93Ghz Mac Pro: £5368
Custom Dell: £4650
So moving up the ladder creates a larger difference in price but either way, at the start the difference isn't that great.
Custom build from parts (for my spec Mac Pro): £1500 (can be less depending on parts, but if I went this way NOW i'd get a decent X58 mobo, 5870, decent Lian Li case, etc. - This doesn't include HD, fans, bluetooth and all the silly little parts you need). Not to mention no 3 year warranty, hassle of fault finding if it goes wrong, etc.
For arguments sake lets say the difference between a decent overclocking computer and my Mac Pro is £650. Now this £650 is only worth it to people who rank OS X and the build quality of the Mac Pro. I do. Would I buy a 2009 Mac Pro again? Yes.
People are complaining that technology has moved on and that the prices haven't dropped, well it hasn't really apart from the CPU and GPU which cost more than the equiv 4 core chips (2.66GHz 6 core XEON = £800 - 4 core = £250ish).
If you NEED 6 cores you buy the 8 core mac pro, if you need 12 cores you wait.
My argument is getting a little messy here but the facts of the Mac Pro upgrade coming are this:
1. CPU choice: Either 6 core chips are going to be added CTO with no change in the rest of the line along with a slight price drop to reflect the reduction in costs of components OR the price will stay the same and all the CPUs get shifted down one. Eg Base Mac Pro will be 2.93Ghz and the top CTO will be the 3.33Ghz 6 core chips. Architecture changes? NONE - As there isn't one to move to!
2. GPU choice: Easy, whatever the low end nVidia is now of the GT120 and a 5870.
3. Rest of system: Maybe space for SSDs, unlikely to add more HD bays, bluetooth may change position.
Waiting will get you a 2010 system, will it be worth the wait? Probably not for the people at the bottom end...
Besides if it really bothers you find one of the many still-in-warranty 2009 Mac Pros on ebay for a cheaper option, then you get more for your money!
