1000fps, stable on the majority of maps. You should expect drops on werk, douze and power near the middle areas of the map, but you should get 800+ on all of the aforementioned maps.
I know this because I also have a 22" 1920x1080 monitor, my GPU is comparable to yours (only major difference apart from the brand names are higher VRAM on mine and higher clock speeds on yours), and this the kind of framerate I get (but I'm playing on high, I noticed no difference in framerate when playing on lowest + high settings, just when I switched to ultra).
Just make sure your PSU is 650w or higher and not a cheap one, then you should be okay. Also in an ideal world you would swap the AMD for an Intel but for AC it's not gonna make a difference since it only uses one core (correct me if i'm wrong) anyway.
