Did some testing:
seems I overestimated framerates, with my settings framerates in shatt are around 20-30fps, enabling 2x AA is possible and costs about 3-4fps, 4x another 3-4fps - so with 4x you're down to around 18fps average which is a bit on the low side.
Minimum settings seems to give a consistent 50fps.
Setting viewdistance to further away leeds to stuttering, seems like it'll need to load textures quicker than it can manage then and framerate goes down the drain - once textures are loaded framerate goes up to almost low view distance levels, but it's still pretty much unplayable as each time it needs to load another new texture framereate goes down the drain again.
These screenshots were taken with the settings below, no AA:
Charging Battery, Playing WoW, Wlan & Bluetooth on: 66W
Charging Battery, Wlan + Bluetooth on: 45W
Charging Battery, Sleep, Bluetooth off: 52W (?? does it go into speedcharging while sleeping?)
Edit: odd...now it's at 30W while charging while sleeping...maybe there's just a spike right when it goes to sleep...
Looking at the deltas here I'd estimate that it uses around 15w in idle and 36w while playing wow, will update figures once it's fully charged and see how it'll look then.
Temps (After about 10min of WoW):
Cpu, heatsink A & B = 71c
Northbridge = 58c
Enclosure Bottom = 33c
HD = 35c
More wattage numbers to follow, didn't feel like powering it down just yet, I'm only at 6 1/2 days uptime
