Which WC Setup ?

[Gaiden133]

I plan on cooling:

• Q6600 G0 OC'd
• 4870x2
• NB (if i do setup #2)

Setup #1

CPU Block: D-tek Fuzion v2 with nozzles
GPU Block: EK Block for 4870x2
Reservoir: Swifttech MCRES-micro or EK-RES250
Pump: Swifttech MCP-655
Tubing: PrimoFlex Pro LRT UV Blue 3/8 ID, 5/8 OD
Radiator: Swifttech MCR-320

Is that too much for a MCR-320 ?

I'm worried that the heat output by the 4870x2 will affect everything else in the loop.

Setup #2

CPU Block: EK Supreme Plexi
GPU Block: EK Block for 4870x2
Reservoir: 2x Swifttech MCRES-micro or 2x EK-RES150
Pump: 2x Swifttech MCP-355
Tubing: PrimoFlex Pro LRT UV Blue 3/8 ID, 5/8 OD for first loop, red uv primoflex for 2nd loop.
Radiator: 2x Swifttech MCR-220

One loop would be just for the EK Supreme since I hear its pretty restrictive.

The other loop would include the EK block for the 4780x2 and the NB EK block.

Only thing is that first, its a little bit more expensive than the first setup.
Second, is it ... overkill ? Third, would there be NO difference in temps between the two setups?
