I have a quad-core @6600 with 2GB of RAM and an ATI 3870 by HIS IceQ Turbo 3. At all maxed out and by 1680x1050 I get very little lag. Though I just entered the wilderness area and get serious stutters. like it just stops. It freezes and starts back up again with my enemy moved 50ft and me at the same spot. Needless to say, this is a serious issue!

Anybody else having the same problem?
