Your PC limited more by the RAM than the newer hard drive. As information is accessed by the CPU, it comes from the RAM, which is faster than the hard drive. If there isn't enough RAM, the hard drive can take its place as a far slower alternative. If you really, really want to keep this PC, I would run something like CPUz to find out the motherboard and look into adding more RAM before considering a hard drive upgrade. The exception to this is if you have simply ran out of space and need more room for files.
