Hi there,
I'd personally opt for a HD5450 or similar, it's very low power (takes all its power from the PCI-E Lane) and completely silent. It also supports resolutions upto and including 2560 x 1600 via Dual link DVI or Display Port

The HD5450 is powerful enough for your needs, the HD6850 is overkill and I wouldn't trust a 350W PSU to power it.

If i go with the R6850 i would use a SuperFlower 600Watt PSU.
It is not overly power hungry, but these systems will be on 24/7 and don't need gaming GPU's.
At what point are GPU's considered out of their 'idle' state (and upping their power draw)? Is it only during gaming? or would HD video playback or graphics apps also push them?

HD playback is no where near as power intensive as rending games, but it will certainly pull the GPU from idle state. Maybe not much but it will. What graphics apps are you talking about in particular? like auto CAD or something?

The likely reason for the limited resolution is because the interface connectors of the motherboard are all bandwidth limited. HDMI can only do 1080p@48fps, and SL-DVI (single link dvi) is not capable of 120FPS at 1080p.
You're driving a resolution that is essentially double 1080p, so you would need a dual-link dvi or display port connector to get the bandwidth required to drive 60fps, even on the desktop.
I can't say for sure if you would be able to get 30fps out of the integrated graphics and still drive the display correctly (I think that you could, but I'm not confident, just educated guessing). If it does work, my guess is that they state the max resolution for 'fair disclosure' because you cannot drive the display at 60hz.
