intel core i5 450m vs 430m for gaming

[aasim]

I am looking for a gaming laptop thats between $1000-1100. I am confused between whether to buy the 450m or the 430m. I want to be able to play games like COD, assassins creed2,battlefield bad company2, justcause2, crysis2,batman arkham asylum and all other most common fps shooter games on preferbly medium to high settings. All i dont know is which proccesor to buy 450m or 430m. 430m is older than 450m by 3 months. Most laptops nowadays I see are coming with 430m so I get scared thinking that 450m is not good but on the other hand i also think that 450m is newer so it might take somew time for more laptops to come out.I know the main difference is clock speed but i think clock speed matters in playing games of now and games of future.
Anyways I live in North America,Canada.

450m is better than 430m, because it is running at higher frequency. Except that, this is same cpu.
But for playing, cpu is not the most important part. This is the gpu which is important.
Depending on the native res of the laptop's display, you might need a high level gpu, because mobiles gpu really sucks most of time. See some benchmark here : http://www.videocardbenchmark.net/high_end_gpus.html
