Specs:
CPU 1,2 GHz
Ram 352 (or something like this)
Radeon 9250 (128 MB Ram - I believe)

Performance:
Turn time: around 3 minutes
Loading and Starting time take forever
But once started Campaign Map and Battles work quite well on low settings with battlesize huge but only with the standard limitations (with reinforcements)

Its somehow a pain in the ass but I'll probably wait to buy a new PC until EB2 is finished ;)

To all EB fans Good start into the new year !!
