The post pretty much describes the situation, but this particular part is somewhat too general.
Workstation rigs and gaming rigs are not all that similar, and while your remarks on the gaming aspect are fine, a workstation rig is a completely different matter.
The needs on situational performance make the cost on workstation builds a secondary matter.
Both Intel and AMD have 2 sockets for their workstation targeted processors. One for low-to-mid end, and one for mid-to-high end.
Now you could get an i7 or FX instead of xeon/opteron, you could even use the extra feature of using an unlocked processor to increase relative performance, but even like that, even when using a hexa-core overclocked 4930k, you'll still be way behind a twelve-core xeon. So essentially you'd relate more to the mid-end position than the high-end when it comes to single socket workstation.
Workstation needs are very different than gaming and office needs. Workstation oriented processors are mostly useless for things like gaming by design. It's a whole different situation.
The 3930k I use here is bundled with a mere Radeon 5850 cause the system here is designed to perform adequately very specific kinds of tasks. It might be considered a high-end desktop part, but for workstation oriented tasks like the ones here, it's merely mid-end. If I had the means to balance the purchase of a 7000$ fifteen-core xeon, I'd even get that.
Also note that even if the cpu here was a 4930k, it's not the best performing processor out there for gaming (the 4770k performs better on most games, even the 4670k usually does) and it's not the best for workstation loads either (those over-priced fifteen-core xeons are).
The mention on purchasing a 7000$ is not a joke by the way. On workstation builds the initial cost is a trivial matter. What counts is how well the processor is going to balance its initial and running costs.Edited by PsyM4n - 3/25/14 at 4:24am
