With a Core2 Duo, you basically have the first 64-bit processor ever used... coupled with the slowest hard drive available. Almost any newer computer will be noticeably faster. I'm using a 2014 MacBook Pro ... but has an SSD, a Core i7 (quad core) and loads of RAM. Even though the computer is now about 4 years old, it's still really fast. An SSD was the one bit of tech that single handedly sped up my computer more than anything else I've ever done to upgrade a computer over the years.
