Hi there,
I use the Gigabyte UP 4 here in the Steinberg Support Department without any issue.
But you should say good-bye to PCI slot.
The time is over for PCI slots and even if you find a mobo with a PCI slot, the performance will be “un- useable” for
an audio-card or a fire wire card. These PCI slots are only emulated as far as I know on modern mobos and the performance is terrible.
For what do you still need a PCI slot exactly?
