Man, expos are dangerous. After dehydrating from drooling over all the cool toys, I eventually settled on a laptop, would you believe. Acer Aspire 6535, 4Gb ram and nVidia GeForce 9600M. I've just been running around Calypso with all settings maxed, and I must say it looks stunning. I'll probably have to ease back some of the settings once I start hunting again, because it is a bit rubbery with all the bells and whistles going, but at least I can see the cool eyecandy if I want. It's a bit of a compromise, but it will also serve well for work, so all round I'm content.
