Although swiftech is a decent company, the rev3 kit is pretty weak from a glimpse of it. The MCP655 is the much better pump compared with the 350, and you can get a better radiator from the dangerden store.
The 6002 block is decent enough, and you can add a GPU block (I suggest the maze4 but the MCW50 is decent enough).
