The workstation PC has some strange choices. It appears to be a gaming PC with workstation cards thrown into the mix. Two low-to-mid-range AMD Firepros that don't even have ECC memory (a must for many workstation applications) is a strange choice. So is a 1500w PSU for a rig that will hardly use 300w. Storage is another concern.
A non-WS series board, non-ECC memory and a CPU that doesn't support ECC memory are also strange choices. That case is more for a gaming rig than a workstation, it's very bulky without giving many features for all that bulk especially compared to something like a Corsair 900D. That said, something much would probably make more sense for a workstation.
A motherboard such as the
Asus X99-E WS is qualified to work with a MASSIVE range of hardware likely to be seen in a workstation, including Red capture cards, Xeon Phi accelerators and more.
The
Xeon E5-2630 v3, an eight core processor with Turbo up to 3.2 GHz, would allow for not only more multithreaded horsepower but also ECC memory. ECC memory, such as this
Crucial 32 GB kit, is an absolute must for any mission critical workstation (i.e. all of them).
The
Firepro W7100 is the same price as two W5100s and will have about the same power consumption, takes one less slot, has zero performance hit in tasks that can't use multiple cards AND is actually faster than two W5100s with perfectly linear scaling. The
W8100 is a better choice as it adds ECC memory to the mix and offers four times the performance on a W5100, but at a price. All of these cards fall flat when using applications that don't support AMD cards, such as the Adobe suite (which is a likely use for a workstation).
Yes it's fun to have an SSD capable of over 2 GB/s transfer speeds, but your storage is very limited and there's NO failover whatsoever. Put four of the
Samsung 500 GB SSDs in RAID 5 for a 1.5 TB partition with more than half the speed of the Intel 750 SSD as well as a larger capacity and then four of these
WD Red 3 TB drives in RAID 5 for a further 9 TB of storage.
Add to that a
Corsair Carbide 330R or similar and a
Corsair RM550 PSU and you're good to go.
Yes, it's more expensive than the rig you specd out (R 70,919) but it has significantly more CPU and GPU power, a LOT more storage, redundant storage and ECC on both the system RAM and GPU RAM.
If you want to cut costs, replace the Firepro W8100 with a W7100 (lacking ECC memory so not the wisest choice), and the SSDs with the
250 GB model. You're then at R 59,718 for much more CPU power, slightly more GPU power, ECC memory, 62 % of the SSD storage at 74 % of the speed with more than eight times the total storage along with redundancy.
