2.8 ghz vs 3.2 ghz

I need speed.

Your words. 3.2 GHz is faster than 2.8 GHz.

You might find this article in Bare Feats interesting (especially the last paragraph of the analysis section).

This article from Macworld is also worth a look because it compares how each of these machines stack up when they are upgraded (RAM and hard drives) in equal measures. From this you might gain some insight as to which upgrades suite your needs and where best to put your money.

Hope this helps.

Hi,
The Mac Pro 2.8 GHz performs so well that you will not notice a difference between the 3.2 nd the 2.8 except that you will be $1600 lighter 🙂

I would suggest putting the $1600 savings in a CD and in two years when you need an upgrade you can use that $1600 plus the resale value of the Mac Pro 2.8 to purchase a new Mac Pro model that is twice as fast as anything available now.

I would only purchase the Mac Pro 3.2 GHz if I had money to burn.

Have fun!

You could save on single cpu for your needs; or Apple Store Specials; and be just fine.

Maybe if you run multiple OSs concurrently in a VM like Fusion... ? and even then the stock 2.8.

Time is money, vs money to burn 🙂
