Thanks for the flowers, but what is now the conclusion for you of this all ?
I could additionally recommend you perhaps this company, which seems to build some nice PCs based on some quality components and using/offering a wide range of Xeon CPUs.

But even then .. firewire is still a bitch .. I would sell the 400 and get UC or UCX.
Here some more details why I started to hate it ...
Even after
- buying now a much better Firewire card
- building a PC based on workstation components (Supermicro board, Xeon CPU, etc)
I still observe, that with the UFX and latest drivers its with firewire still not possible to use any possible combination of Sample Frequency and ASIO Buffersize.
With USB it simply works and if I may trust Cubase 7 / 8 then the latency is even a little bit smaller when using USB.
Some time ago, before getting the UFX, when I had a Focusrite LS 56 you could have described me to be a Firewire advocat, as this protocol appeared to me from design perspective the better protocol.
Devices with own intelligence. Which lead to a smaller less compless and cpu intensive driver on the host side.
But even there with the Focusrite I had to struggle to get a proper device in terms of chipset, but it worked.
When switching to RME with rock solid low latency drivers I experienced this issue, that not all sample frequency/ASIO buffer size combinations worked. Then the "dance" began ... find out why ... Not that the unit didnt work, but as a techie its kind of unacceptable to this undeterministic behaviour.
Then I found out, that switching to different PCIe Slots on the old mainboard (P55 GD65) lead to slightly different results. Finally I was really sick of this and as I anyway intended to upgrade my system I did a system upgrade by using workstation components, as in an other forum there was an advocat of using server components and he recommended a certain company, which unfortunately simply was to expensive for me.
Now with the new system I hoped/expected to get entirely rid of this firewire problematic.
The new system works phantastic, but one thing remained, its still not possible with firewire to use all possible combinations of Sample Frequency and ASIO buffersize.
I am really tired of this topic and it simply nerves as from my perspective something like this shall not happen.
Bought many different Firewire quality cables, Firewire interfaces with VIA and TI chip etc etc ...
So it can still be everything .. RME Driver, Firewire Chipset, Design of mainboard, or even the phase of the moon.
I became pragmatic and am using USB now. At least for me this "undeterministic behaviour" is somehow unacceptable .. Good-bye nicely designed protocol, but in practice behaves like a bitch...
