It'll be okay for playing. I have a somewhat similar notebook (albeit with an nvidia card that's one generation further, although I had one with the 9xxx series before as well), and you'll be able to run SH4 fine on it as long as you don't expect especially outstanding performance. I found that after turning off volumetric fog and some of the post-processing effects the FPS was more than acceptable, and generally the more you turn off the better it runs. SHIII you'll have no problems whatsoever.

IL-2 - well, maybe it's just me, but I never quite got it to run well on a mobile rig of those specs. Maybe I just had some of the settings really wrong, but it always seemed more choppy to me than it should be.

Be advised that the video card will always probably be a bit of a bottleneck in performance (it may say so on paper, but it will really never be an equivalent of a real desktop 9800 - so be ready to sacrifice some graphics settings in games) and will run VERY hot - careful where you place the PC, make sure you're not obstructing the vent, and consider setting it up on some sort of raised support or little cooling platform (that just allows air to get under the computer more easily). My previous laptop died after the video card overheated and blew - and because on laptops the video card is just a chip on the motherboard, that meant the whole PC had to be written off for dead. So, learn from my lesson and watch the heat!
