Finally new macpros.

So for those in the know, can you inform 'us' users who have been sitting on the fence about buying a new machine, should we buy one of the new machines or get pick up an old one before they are discontinued. Should i go out now and buy an old 2.8 Octo core, at a good price.. or should spend the extra money and get the new single 2.66 quad core machine? Using the machine for XDCAM Ex/P2 Editing with the occasional uncompressed 10 bit SD work. Going to be putting a kona LHe card in whatever i buy.

The new 2.66 is $500 usd more expensive than the old 2.8 down here and probably close to that in australia..

I'd go with the more physical cores. The new architecture is nice but it's not going to make up for missing 4-cores when compared to the previous architecture.

Ditto on that Joe...I too am considering either a Windows only machine with the i7 920 cpu or one of these new MacPros...probably just the single cpu (quad core) configuration.

I'd like to see some comparisons (editing, rendering, 3D compositing, etc...) of the both the (single processor config) Quad Core versions (2.66 & 2.93) vs. the current desktop i7 on the Windows side (920, 940, 965) line up.

The "dual processor" configs are nice, but just a bit pricey for the slight performance increase that it states on the Apple website....at least it's pricey to me.

Funny, looking at the MacPro tower they eliminated FW400 and just went with FW800 and USB2.0. Would figure they would have included HDMI (which you can do via a DVI - HDMI adpater from your graphics card) and an e-SATA port. Seems like the "Windows Only" machines give you a few more connection options on their motherboards.

But I suppose the bottom line is the apps you want / need to utilize for your workflow.

After speaking with a few people down here the thoughts are there wont be a refresh to far off from these ones, end of the year max, with dual octo cores, so i think im gonna pick up an old 2.8 machine at a good price while i can. Save some dollars.

Does anyone know if the single processor Mac pro can be upgraded to a dual chip machine, including the ability to host more RAM as the current dual chip can?

If you're primary software isn't optimized for multi-processor use the new machines may be better - they have a 'turbo' mode where if they determine that one core is handling most of the load they can disable the remaining cores and overclock the single core to optimize performance.

Isn't this just a small percentage increase in performance and still no blu-ray support?

Depends.

Nehalem the core architecture can encode some files at %40 faster than previous Xeon Penryn procs.

Geekbench score on the 2.92ghz hit 17,6000: MacPro4,1 : Geekbench Result Browser (http://browse.geekbench.ca/geekbench2/view/115605)

By comparison, the previous generation 3.2ghz maxed out at around 11,000: Mac Pro (Early 2008) : Geekbench Result Browser (http://browse.geekbench.ca/geekbench2/view/115744)

So no, I'd say it's not just a small percentage increase in performance.
