speaking of Crysis, I've been messing with COD Black ops, and while the gameplay is there, couldn't help feeling graphically it's way behind even Farcry 1, let alone Crysis 1... (Still looks like DX9 console port) if you don't happen to mind short ON-RAILS (One of the most on rails ones I know in fact) FPS gaming, however this is one is better than MW2 in my view, although that's not a huge task to beat.
COD BO (Body Odour? peeheww!) Runs very nice using the Morphing AA, but the levels are often very short and while theres certainly plenty of story to fill that, it does stop you getting into it on the same level as Crysis or Bad Company 2. So looks like Crysis 2, Bad Company 2 Vietnam (funny they pick same theatre as COD BO...lol) or Battlefield 3 will do the business on PC high end gear.
