And I would like to apologize to those of you who mistook my statements on CPU power as a negative comment on integrated Macs. I am quite impressed with the Mac Mini and its overclocking ability is astounding.
Currently, I use an eMac because its cheaper and only slightly slower (both these systems are faster than a much more expensive Pegasos).
But neither the eMac nor the Mac Mini has upgradable graphics.
Years ago I had both a Radeon 9000 Pro and a Radeon9500Pro (which is basically a 9700 with a 128bit memory bus). The 9500 ran circles around the 9000. I kept that card longer than any other video card I've ever owned.
When I replaced it, I bought an X800 and then later a 3850.
My processors have only improved in small amounts, but in some of my software now produces fps ratess 5 or 6 times higher.
Right now, we have fairly good processors (with the hope of even faster processors in the future). Its time to move forward to more powerful GPUs.
