"With no mechanical moving parts, no spinning platters, and just really fast flash memory, a SSD is likely the best upgrade that you can perform on your rig due to the storage subsystem being the slowest part of the typical computer system."
Uh, what? Unless your only task on the computer is loading software (and not actually using said software), an SSD does not buy you very much. If you game, that extra $200-$400 would be better spent on a GPU or CPU. If you create content (videos, whatever) you need more storage than an SSD even has. If you don't do anything very intensive, just save yourself the money.
