New MP: less bang for a buck?

[toke lahti]

Has anybody compared new 2009 MP's pricewise to older ones?
Like 09-MP-2.26 ($3300) vs. 08-MP-3.00 ($3500?)?
Or 09-MP-2.66 ($4700) vs. 08-MP-3.20 ($4200?)?

Are my prices right for 2008 MP's?
I'd be really interested about power with FCS2/Color/Compressor...

edit: I meant comparison between 8-core MP's.

Better architecture for memory hungry apps, and a memory DIMM that'll be cheaper than the FB-DIMMs since it is used in a wider variety of machines.

You can't really compare processors based on the clock speed. Read this (from the front page): https://www.macrumors.com/2009/03/05/apple-gets-nehalem-early-h264-and-vmware-performance-boosts/

Not yet. The 2.26GHz Mac Pro is the confusing system, but the 2009 dual 2.66GHz offers more performance than the 2008 3.2GHz Mac Pro. If you are looking at spending ~$5,000 or more go with the 2.66GHz.

This is also worth a read,

Which goes to show that it looks like the old 2.8 octo may very well outperform the new 2.66 nehalem quad, but not as much as their clock and core count would have you believe.

So comparing the 8 core machines against each other could very well show the nehalems to be better performers and maybe worth the additional cost, we'll have to wait for some benchmarks to see by how much though.

Cheaper memory is very good point in price comparison.
How much less reliable are new non-FB?
What is price ratio between old FB and new non-FB?

There are no reliability differences.

OWC have prices of 8GB DDR3 for $150 and 8GB FB-DIMM for $188. Those are for 2GB UDIMMs, 4GB RDIMMs are more expensive and Crucial currently have them for $187 for a single 4GB module with their price on 800MHz FB-DIMMs at $180 for a 4GB module.
