Hi, the processor of the this model Vaio is Intel Pentium Dual-Core T2310. This is a 64bit processor which means that it should support a 64 bit operating system. Whether it will come with a 64 bit operating sysem, depends on your order.
Here are two links with the processor specifications and the Vaio specifications:

If you already have one, you can check if it is a 32bit or 64 bit by clicking on: Start/right click Computer and select properties.
