Nathan, Do I think it is possible to upgrad the CPU on this laptop? Yes I think that you will be able to do. Do I think that you are going to be able to put a Intel® Core™ i5 or Intel Core i7 processor in it? I really don't know. You are going to have to check with Toshiba what this laptop's motherboard will support for a processor upgrade along with the cooling handle a more robust processor like an Intel Core i5 or Intel Core i7. You can reach them at 800-457-7777.
