It's no gaming machine. Look for one with 8400, 8600 or higher versions of the Nvidia chipset. In fact your 9600 should outperform the 7150 equipped laptop.
I have a notebook which has 512Mb RAM with an ATI Mobility Radeon 9600
graphics card. I have to buy another laptop and the one I am looking at is the Acer Aspire 5520 which has 2GB RAM and a Nvidia GeForce 7000M graphics card. Will the Acer perform as good or better for motor race gaming? Your comments would be most welcome as I do not know the subtleties of gaming chips.
