Default Intel Q45 or nV 9x00 as base for NAS/GP Server

Hi,

I'm trying to decide between the following motherboards from the following chip-set families...

nVidia MCP 730i/Geforce 9400:
This is pretty much the only decent option in Australia (Gigabyte's not available)
http://www.dfi.com.tw/portal/CM/cmpr...rmal&mode=view

Intel GMCH82Q45/ICH10DO:
I'm yet to decide between these two (Asus not available in Australia) but I'm erring more towards the Intel board:
http://www.gigabyte.com.tw/Products/...ProductID=3034
http://ark.intel.com/Product.aspx?id=34687
Mainly because there's no guarantee that GB will provide BIOS updates every time Intel's apps/firmware is updated...

I need to work out which chip-set is most suited for my intended application, and a big part of that will be determining which has the best support in the OSS world.
If possible I'd like to implement a bare-metal hypervisor that will allow me to have multiple simultaneous specialised environments running; the 1st of those being a NAS.*

Power management/efficiency of the two chip-sets seems to be a fairly close affair...
At idle the Intel chip-set has a tiny advantage but at load they're equal, brownie points to nV because at load it's IGP wallops Intel's yet it draws no more wattage!

When it comes to IGP's Intel's G45 (superior to the Q45) gets thoroughly walloped, but this is of little interest to me.
I'm more interested in performance disparities -if any- in terms of: Memory, e/SATA, RAID, USB, Ethernet etc...

According to most reviews (Windows based), Memory & SB I/O performance is very similar between the two chip-sets, although nV seems to win just in most areas.
Apparently the leads are so tiny that it's unlikely the differences would be noticeable in real world applications...

This may be a very different situation in GNU/Linux, *BSD, GNU/Solaris etc. but if not the choice becomes clearer in favour of nV!

However...

If I choose the nV platform it seems I lose the following which are part of the Q45 chip-set (not just the CPU):
Intel VT-d, JTAG boundary scan, Intel AMT 5.x Pro, Intel TPM 1.2

I've read-up on the aforementioned features and some of them are pretty darn cool...
Perhaps the coolest (as far as I understand them thus far) is VT-d...

This I imagine would be very useful if I were to implement the bare-metal hypervisor I spoke of earlier....
All four of are part of the core-logic of the chip-set and I'm not sure there's a decent substitute for any of them!

According to some adverts Intel TXT is available to the nV chip-set, I'm yet to confirm but this feature may only rely on CPU selection.

Just interested in others thoughts on where to head to from here....
Particularly those who've had lots of experience using Intel 4 Series (preferably Q45) OR nV 730i/9x00 motherboards in "*nix-land"!

Cheers
Jed
*will prolly try FreeNAS 1st

I've decided to change tack, and have subsequently received some amazingly in-depth feedback in the thread below.

SOHO Bare-metal (native) Hypervisor; best Chipset/CPU combo?

A interesting read if you're thinking of doing something similar!
