Mate,

Do you have a quad core, or a dual core. I assume Dual. A dual quad is confusing.

I have a dual core overclocked from 2.4Ghz to 3.4Ghz, and I'm running an overclocked 8800GTX. I'm not running everything on Ultra because I too would be in the teens. My resolution is also 4:3 format at 1600x1200.

I've seen an increase on the campaign map from 26 to 34 fps to 40 to 45 fps. In the Land and Sea battles it's more variable but there is an increase for sure at least 5 to 10 fps. The increase is enough for me to consider increasing some of the settings or upping the AA or AF.
