The simple fact is - the new Mac Pros, especially in Europe, are very, very, very bad value for money.
Two weeks ago you could buy MA970 (base 8 core 2.8Ghz Harpertown spec) from resellers from as low as £1559. Apple Stores had them for £1760 on day one when they were rolled out, £1719 when dollar dived to $2 per £1. £1711 on the last day, before they introduced Nahalem Mac Pros.
Base spec, single CPU, quad core Nahalem 2.66Ghz '09 Mac is now £1899. It can't be upgraded to 8 cores, it won't take more than 8Gb of memory, and at £188 premium it is to "old" 8 core Harpertown '08 mac pro what Chevrolet Aveo is to the Chevrolet's muscle cars. It's about as serious alternative to old base spec MP as Jon Stewart offering to stand for Vitali Klitschko in boxing match.
The next workstation up - 8 core 2.26Ghz Nahalem (which we now slowly discover is about the speed or even slower in some benchmarks than "old" Harpertown 8 core) is £788 more expensive than the former. One thousand, one hundred US dollars. For machine that's no faster than last years spec. Have a moment to process that - eleven hundred bucks - just think what you could upgrade that Harpertown to for that...
Regardless of how many times you read i7 spec sheet, and how many tantrums superpalmtree throws and how many one line quotes he replies to, to up his post count, buck for buck the new lineup is simply a horrible deal, especially the bottom spec single CPU mac pro - it is below par offering in jester's suit. The price difference is crazy. Insane. It's a rude joke in bad taste, especially in current economic climate. Almost 800 pounds more for machine that's no faster than last spec. Borderline outrageous. End of story.
There is nothing in Harpertown spec that would stop it from serving well for years to come. There is nothing weak about 8 core monstrocity upgradable to 32Gb of RAM and Ati 4870. Not under windows, not under OSX. Not even in server room. Not unless you do some crazy 0 minute number crunching where 10%-20% gains are worth paying $1000 for. There are no milestones in i7 architecture that would require anyone to switch immediately right here, right now. No changes that would render last year lineup obsolete over night. There will be no ground breaking modifications to OS that would suddenly advance benchmarks far enough to make you think that £800 extra was well spent.
At £1711 last month, compared to competition, Mac Pro with 8 core 2.8Ghz was great value, beefy machine to do work, editing, rendering on OSX, and gaming under Windows. At £2499, compared to competition, 8 core Mac Pro 2.26Ghz is a pretty poor spec with one heck of a crazy pricetag.
Just my 22 pence worth...
