More aboutcore t9300
Yes all Intel Core 2 CPUs support x64
You should also check with the laptops manufacturer to make sure the motherboard and other components are also supported under Windows 7 and ask if they support both x86 and x64. It takes more than just CPU support to run x64 applications...
