Sounds like the requirment is dual core for the new BiA. I know a requirement means what it means, but is there anyone out there who's tried it with a single core PC? This is a real bummer, I was willing to get this game and even play it at low settings.

3500+ AMD 64
2 GB ram
6800 gt 256 mb

People have reported being able to play with only a single core CPU, but it may prove to be like Assassins Creed, which also had dual core as the requirement, single core users who could play at decent settings all seemed to have video cards that were above the minimum listed.
You have a card at the low end of the list, and if it's an AGP version as well, with lower bandwidth, you may find you get problems.

yup, it's an agp. bummer. an upgrade probably ain't gonna happen. especially since this is the only game i really would upgrade for.
