First off I greatly appreciate any support and time involved in answering these questions.

I'm trying to decipher some results on the internet as you can't believe everything. Is there a better place to research out builds. I've been looking in places like this one. http://www.passmark.com/baselines/top.html


I've been looking at some processors and I'm confused on some statistics

I can buy a dual Xeon E5-2643 computer for 850$(not a bad deal) or I could get a home built i7 build with an i7 3930K

According to cpuboss.com the passmark score of the i7 is up to 4.5 times greater when overclocked, yet they are basically equal when stock built. Is this BS, or can one expect that much of an increase in power when properly overclocked?

Edit: Computer will be used for a workstation, looking to get speed for 3D rendering

Well, a workstation usually means a workload and that usually means as many threads as possible.

Rendering on the other hand can use the CPU, the GPU or a combination and is dictated by the
software applications that you use. That raises the question of a professional lower spec card that
costs as much or more than a consumer card of up to four times the spec but not having double
precision drivers. ECC RAM is also part of the equation.

For single effort the fastest single CPU combined with 32-64 GB of RAM and the most GPU you can
afford will give you the best result.

Having said that sometimes it's multi-threadedness that carries the day and the workload of having many
tasks on the go as well as several projects.

The place to start is with the applications you use. What are they and what are other people using to
deal with their hardware needs? It's all well and fine to have the best specs but what does that equate
to in terms of hours and minutes?

For GPU based renders does a dual Fermie GTX 580 + a Kepler GTX 780 Ti match a dual Maxwell GTX 980
setup? How about the $1200 Titan with 12 GB's of RAM?

The next thing is the budget. Dual Xeon E5-2643's in what configuration? Is that used for $850?

What kind of build goes with http://cpuboss.com/cpus/Intel-Core-i7-4790K-vs-Intel-Core-i7-3930K?
