Just wondering if the Mac Pro 2008 8-core is slower then the new IMac 27" I7. I'm about to buy a new computer and this is a major factor. Sorry about all the computer questions but I'm doing a big project in 3D (over 3300 frames) and I need render power. The 2008n 2.8 8-core Mac Pro is nearly 3 years old vs a new intel chip in the IMacs and I'm not sure the power difference for rendering.

The mac pro would be less likely to overheat during constant rendering and would probably be almost as fast...you can load it up with plenty of RAM too. The downside is that it will consume more power and won't have a built in screen (if that is a downside?).

I'm sure you don't want to hear it but if you're purely looking for render power I'd buy 2 or 3 basic i7 PC's instead. You can buy barebone i7 rack chassis for a couple hundred bucks, put a CPU, RAM and cheap HD in there and you've got a render node for about $500- $800.

if you look here in the Cinebench test the 8-core is a bit faster, but has no built-in 27" screen : http://barefeats.com/wst10.html

Problem with that is all my audio and video software is mac based and I just can't work on a PC. I'm a mac OSX guy all the way. Thanks for the info but it would cost me thousands to switch over.

Just wondering if the Mac Pro 2008 8-core is slower then the new IMac 27" I7.

Having used both, even the 2.8Ghz Early 2008 renders faster than the 2.93Ghz i7. If you can get a 3.0Ghz Early 2008 Mac Pro then there's no comparison between the two.

BTW, be extra careful with iMacs. There are a lot of reports about the screen developing dark splotches when overheated. And it happened to mine as well.

Hope this helps.

Hmmmm, that's good advice. Thanks. I would love the 3.0 but I only have about $2200 to spend and even on Ebay they are selling for more then that not counting the screen. What do you recommend?

Hey what do you think of this. MAC PRO 3.0 GHZ 8 Core 4GB 960GB GeForce 8800 AXP 3,1
Is this something that would make sense for rendering? I saw it on Ebay for $2100

There maybe some useful info buried in here http://macperformanceguide.com/Reviews-MacProWestmere.html

I think if I end up buying a Mac Pro, I may get the Dell UltraSharp U2410. It's a 24 inch but I've had the 2407 from Dell in the past and it was a great monitor. I just don't have $900 to spend on a 27 inch but a 24 inch should work fairly well. What do you guys think?

Yup, I use that as well as a 2.8 at work, and they are really fast. Of course technology has evolved since then, but the "3,1" generation still performs well. Memory is also cheap nowadays.

You're advice has helped me make a better long run decision and get a Mac Pro. My wife is getting a 24" IMac from 2008 but she only uses text programs and checks her email. No high heat renders on her machine so I'm not worried about that one. Me on the other hand, I always seem to push my Mac machines to the limit. LOL I've decided, because it's so vital to my recent projects and business which includes tons of audio tracks, virtual instruments, Photoshop, and LW rendering (and I hate compromising in quality if I can help it), the Mac Pro just makes more sense. It's more expensive getting that and then buying a quality monitor but if I plan on keeping it for 3-4 years, I need to get something that is known to be a work horse, not overheat, and last a very long time. Thanks for telling me about the heat to screen issue. That would be horrible. Specially in the graphics market.

You'r welcome. I got myself an iMac for home and became aware of the screen issue only after seeing the first blotches. Wish I knew about it before!

Yeah, and I'm sure that hasn't been fixed on the newest 2011 model set to come out soon.
