I've enjoyed following all the Nehalem mac pro discussions here the past couple weeks. Regardless, I've not been convinced to purchase an '08 2.8 Harpertown Mac Pro Octad over an '09 2.26 Nehalem Mac Pro Octad despite prevailing opinion of regarding value per performance. I'm building an edit suite. This will be my first Mac Pro. I'll be using FCS2 FCP6, Motion and Color, as well as CS4 and Soundtrack, possibly Shake. The '09 2.26 octad with 4870 is the most I can afford at the moment since I have other hardware peripherals to purchase in this build. The '08 2.8 octad upgraded to similar spec comes in only £400 cheaper. I want something I can build on, and possibly upgrade, to remain fully competent for a good few years (~4-5 hopefully). I'm prepared to call this Apple specialist video systems specifier tomorrow and close the deal. Any dissenters? I still have a finger on an '08 2.8 octad... last chance to convince me I'd be better of with the 2.8 octad. Likewise, I'd appreciate any feedback regarding why the '09 2.26 octad might be a better choice.
