okcnaline :
The only problem I have with Xeon E5 is that they have low speeds and high prices.
With 8 Cores:

okcnaline,
Xeon E5 that are configured for multiple CPU's are typically expensive when having high clock speeds, but the E5-1600 series are fast and reasonably priced, e.g., the quad core E5-1620 v2 which is 3.7 / 3.9GHz for $295 and the six-core E5-1650 is a 3.5 / 3.9 at $580. I think you would agree that 3.5, 3.7, and 3.9 GHz CPU's are not slow processors.
For comparison, the quad core i7-4820K Ivy Bridge-E 3.7GHz / 3.9GHz costs $325 and the six core i7-4960X Ivy Bridge-E 3.6 / 4GHz is $1,050. In both cases, the Xeon of similar clock speed is less expensive than the equivalent i7. Of course, the ability to overclock the K and X models is useful in gaming, but not in a workstation use because of the long running times using all cores and other reliability factors.
As well, it's important to remember that this thread concerns a system of $1,200 total cost, so there is no consideration of dual processors or 8-cores.
I like AMD processors for their great cost / performance, and the clock speeds are good- though not higher than the 1600 Xeons- but AMD do not have the same calculation density not memory bandwidth of Xeon E5's. On Passmark Performance Test >
AMD FX-8320 8 cores / 8 threads Score = 8101 Ranking = No, 102
AMD FX-6300 6 cores / 6 threads Score = 6387 Ranking = No. 187
E5-1620 v2 4 cores / 8 threads Score = 9546 Ranking = No. 52
-plus the LGA2011 socket can be upgraded to a true 6 core 12 thread or 8 core / 16 thread CPU
And, as well, the way cores are counted, the FX-6300 would be the equivalent number of threads as a 3-core Intel- if they were made- and the FX 8320 is of course the same as a hyperthreading quad core Intel. The FX-8320 has about 15% lower performance but at $100 less- so the cost / performance is significantly better. Still, for this CPU intensive application, it seems more important to have a solid CPU foundation and the ability to up the thread count.
