Just a quick summary update:
It arrived yesterday!
ordered 16th
shipped 24th via DHL
arrived in the country on the 26th, delivered 27th morning.
Side note: DHL's online tracking is horrific. half the time you have no idea where your package is.
LG display but no IR problems.
Mountain Lion is gorgeous at best, bearable at worst and no where near as bad as i thought non-retina upscaling would be. windows 7 in a virtual machine running at 1440x900 full screen actually looks nice as well.
Bootcamp on the other hand is a nightmare. No native 1440x900 res, has to be manually entered as a custom resolution. native resolution looks best, but isnt useable. DPI scaling is horrible under windows due to inconsistencies across visual elements (ie icons, buttons, text and images). some things scale well, some dont at all and some stay at native resolution regardless.
Guild Wars 2 was my first graphics stress test. Have to say it, the 650m is a little shorthanded. 15ish fps at max resolution and max settings minus AA. Looks gorgeous, isnt playable. scaling down settings didn't improve perfomance as much as i'd have liked. between 30-50fps. Will try other titles later. Apple should have added a 2gb vram option for the resolution.
