I understand what you're saying and I've worked with computers many years, I've been fascinated since I was a child. I must have looked at the wrong list, because I thought they were still using LGA 1366. I'm spending my free time on this, I've been pretty busy this week volunteering, interviewing, producing.
Dmitri's Blog is Great, I love it, he's very smart, and I've taken some of his ideas into consideration. I'm polling from multiple sources, and my own experience.
Workstation builds with Xeon aren't worth it unless they're $5000, because of the price for entry isn't as powerful as top of the line i7.
I use Intel Extreme workstations at school, it's extremely satisfying watching those boxes go around and reveal an image, these computers are 4 years old, would I buy one? Yes, but at the right price. http://www.arch.rpi.edu/school/digital-lab/
Intel Core i7 980 Extreme w/ 6 dual-cores (3.33GHz, 12MB Cache)
There's fast enough, and then there's fastest. Fastest doesn't last long and future technology will be better. I'd rather spend less now, and swap parts out, putting $200 in a year.
Here's the last CL, you don't need to click, I posted the specs below, I won't pay $2000, but anyone with an i7 wants a premium, my laptop (T530) has an i7. It doesn't exactly slaughter renders.

I try to keep the responses short, but it leaves them open to interpretation. Thanks! What can I say, I love craigslist?
