Nihaal Manesia on a powerful Mac not even sold by Apple:
The Mac Pro is a high-end Mac with a high-end price, but it is not the most powerful Mac available on the market.
Mac Pro is not even Apple’s most powerful Mac.
There is a small community of creative professionals who are taking their 2009-2012 Mac Pros and modifying them to be even more powerful than the computers Apple sells today. The older Mac Pros can use top-of-the-line graphics cards, which are not compatible with the newer Macs, allowing them to crush the benchmarks, even when compared to newer computers.
Think Hackintosh. Dell could make some good money by ensuring a Hackintosh mode on Dell PCs.
