Mac Pro
I sold my Quad G5 (5GB RAM) this week for $2500. I am now running a 2.66 Mac Pro with 5GB RAM. Photoshop *IS* slower on the Mac Pro but is still very usable.
I had the Quad and the Mac Pro sitting side by side for a week and ran several tests. On Photoshop, the Quad is quite a bit faster. But, when they update Photoshop in a few months, I am positive it will be faster than the G5, especially if Lightroom is any indication.
I process images from my 1DsII regularly. At 17MP they kill any machine, but the MP handles them fine, even in Photoshop. Adobe Lightroom is a Universal app and performs very nicely on the MP and is faster than my Quad on the same files.
My thoughts:
Positive:
- Most of the new software is Universal so the future software will be nice and speedy on the Mac Pro.
- The existing Universal apps are VERY quick, even when compared to the G5 Quad.
- The Mac Pro uses less electricity
- The rumor is that we might be able to upgrade the processors to quads
- The Mac Pro is MUCH more quiet. Other than the 1900XT fan I can only hear the occasional hard drive access. The G5 Quad was related to a dust buster
Negative:
- 4GB of RAM is outrageous. I paid $800 and Apple charges > $1000.
I would personally much rather have the Mac Pro. It gives you a platform that will be viable for several years to come instead of one that is in decline.
Get a 2.66 with 3GB of RAM then upgrade the RAM later when prices fall (if they ever fall...)
Good luck!
