I have fast and best and it works.
It's my living, and even the fastest machine is slow when you design in 3D. For me its a trade off in productivity. I don't mind a just out of college engineer on an older machine, they don't cost as much and they can't go that fast. I measure tool cost in productivity and, for me, good tools = more $. A lot more than their cost.
Now I wish I was a driver. I could justify a BMW.
