content: The bottle-neck is always going to be the hard drive. Consider that there are different levels of memory Level 1 and Level 2 cache are on the processor itself. Then you have system memory. Then you have Swap which is on the hard drive. Accessing Swap is magnitudes slower than accessing System Memory and even that is magnitudes slower than accessing Level 1 cache. So, having a faster SSD is going to minimize the latency, at least a little bit. It probably won't be noticeable for someone using a word processor, but if you are doing memory intensive work, yeah it's probably worth the upgrade.
