Here are the specs:
Motherboard:
DFI NF4 Infinity nForce4 Audio/GB-LAN/IEEE-1394/PCI-E/SATA/DDR/ATX 64 939
I don't know the current status for nForce4 motherboards, but when I bought my computer last autumn there was a recommendation not to go for NF4/PCI-E/SLI mobos for single processor systems (including dual cores) because of performance problems. Please see this test on RME's web page.
I don't know if this would apply to your choice of mobo. I've not been following the development very closely since, so things might very well have changed and I don't mean to scare you. I would check out the sites that Tanuj linked to above and see what they suggest for a X2 4400+ processor (same as mine btw). I went for an NF3 board, but I'd rather have chosen an NF4 board if I knew some that were working without problems. Another thing to think about when it comes to motherboards seems to be MIDI timing, but I think checking "Use System Time" in the nuendo settings will fix any such problems.
Best,
Nils
Edit: I found some slightly more up to date info about PCIe motherboards for DAWs.
