I got my real-world benchmark, as I had ordered my Dual 2.8Ghz Quad Core Mac Pro on Tuesday. It came and I set it all up yesterday.
Here is my Real-World benchmark... you ready?
F**king FAST!!! So much so, I got bugs in my teeth.
But seriously, I still think it is a bit early to tell. I mean, we have to receive updated software that has been optimized for SSE4. But so far, on my end, it's all good. I am so glad I toughed it out and waited for this batch of Mac Pros to come out. I was seriously struggling by the end of this year, aching to make my purchase. My poor little G4 is sitting in the corner, retired... kind of feel bad for the little inanimate object that served me so well.
I feel the same way: I have a G4 400 that I've had for the last eight years, that has served me extremely well. Just ordered a new Mac Pro and, according to Apple, should be receiving it by February 18th. I have to admit, as excited as I am about the new computer, I feel a bit bad about giving the G4 to a friend of a friend. Sigh.
