Please tell me the diference with hackintosh versus Real Mac!!!!!!
A lot of users can decide follow your way.
I have both a hackintosh and a 2008 Mac Pro, one at work, one at home:
Hack: GA-P35-DS3L motherboard, Q6600 (Core 2 Quad 2.4GHz), nVidia 7800GT, 2GB RAM
Mac Pro: 2xQuad 2.8GHz Xeon (8 cores), nVidia 8800GT, 6GB RAM
Both are running 10.5.2 vanilla, the hack with some custom kexts. They have different hard drive configs, but for the sake of this assume that doesn't matter since I am not short on disk space on either, and they have similar speed drives. Both are attached to identical displays: a 30" Dell 3007WFP, and a 20" Dell 2001FP, and I have the same keyboard and mouse attached to each.
The nutshell is that in general, I can't tell the difference between them. The hack is a little louder with fans than the real Mac Pro is. Obviously I have more RAM and more CPU cores in the real Mac Pro, but for 99.9% of what I use the machines for, you can't tell the difference. VMWARE is the only thing that pegs CPUs, and it doesn't seem to be well threaded (I have MenuMeters installed on both machines, so I can see the CPU usage, and it's all on one core at a time... as a side note typically all cores are under 5% usage in both machines). About the only real difference is that while the real Mac Pro alerts everyone around that I have a Mac on reboot with the signature "BOOOOONG!", on the hack shutdown/restart doesn't work (it'll stop the OS, but the computer won't power off or restart.) I could prolly fix that if I cared, but the machine stays on for months between reboots, and a press of the reset or power buttons works around the issue.
Anyway, the Mac Pro is nice in that I don't have to futz with applying updates, but if you're willing to be careful with Apple updates, and are not trying to render a Pixar film, you can build a hack from supported components for a fraction of the cost of a Mac Pro, and not notice much difference in performance. It'll be louder, and it won't have the engineered Apple case, and updates will be sketchy, but it'll work and work well.
