I always have so much trouble deciding where to post....CPU? Motherboard/Chipset? System Builder's Anonymous? You can almost never talk about one component to the exclusion of all others.
Anyhow, I would like to know if there are people here who are using two E5-26xx CPUs in a workstation
type of system (as opposed to a server). I am curious about hex and octa core systems and all of the reading material that I'm able to find doesn't really help me understand on an "apples-to-apples" basis.
Currently, my budget does not support spending $1200 on two E5 CPUs or $600 for a motherboard. But I am curious and would like to learn more about this type of system. My usage interests are DAW, animation/3d rendering, and folding.
For the two examples below, I tried to pick processors with the same number of cores and roughly close in speed and price, and I would assume either a Geforce 680 or 690 as well as 64 GB RAM and competently fast HDDs or SSDs.
______________________________Example E5 system:
CPU: Intel Xeon E5-2630
Motherboard: ASUS Z9PE-D8 WS
Dual LGA 2011 Intel C602
______________________________Example i7 SB-E system (this is actually what I am planning to build):
CPU: Intel Core i7-3930K
Motherboard: ASUS P9X79 WS
LGA 2011 Intel X79
Question 1 - How much better could the E5 system be expected to perform for multithreaded applications?
Question 2 - How much more electricity might it cost to run a dual E5 system such as the example above?
Question 3 - It seems like the industry is trending toward UEFI but it looks like server class E5 motherboards don't support UEFI. Should this be a major consideration?
Question 4 - If I were to build a dual processor system, I'd like to plan on keeping it in service for 5+ years. Is this a reasonable expectation?
