Your processor is a Willamette-cored P4. It's also either a Socket 423 or a Socket 478 chip. If it is a 423 chip (which I suspect it is at only 1.6GHz), there is no real viable upgrade path other than getting an entirely new computer. If, on the other hand, it is a Socket 478 chip, than upgrades are possible, but as previously mentioned, it depends on the FSB speed of your chip, which can be determined using CPU-Z.
