Benchmark History?
Does anyone have a good history of Apple Benchmarks?
I'm comparing two plans:
A) Replace MacPro's every 4 years.
B) Replace iMac's every 2 years.
Lots of things change over that time scale.  I can throw a _lot_ of money into the best tower available and keep it for a long time, or I can get a "good" consumer-level system and replace it more often.  A 2-year-old iMac will still have great value elsewhere on campus.
I've found this so far.  But, with changing processor versions, memory speeds, etc., the CPU speed is not a good comparison.
