The king of radiators is the Thermochill PA series; I'd say get largest size your case can hold. Tubing, you should use the 3/8 size tubing. For a pump, I personally use the Swiftech MCP350; you will need a reservoir for it as well, I use the Bits Power top/reservoir for the MCP350. For a CPU block you should consider either the Fuzions [v1 and v2] or the EK Supreme. Finally, for your future 9800, you should research what is the best block for it, usually EK makes really good blocks.
