Hello, has anybody played "Armed Assault 2" in Boot Camp on an 27" iMac i5 or i7? Is it playable? On my Macbook Pro (8600 GT) it's totally unplayable even on lowest settings. Also, is it possible to overclock the ATI graphics card? I regularly overclock the Nvidia Card in my MBP which gives a noticeable improvement in 3D games... A.B.
