Will a 2x120mm radiator enough for this?

I am running my i7 920 D0 at 4.0 with 1.22vcore on air. Its about 50C idle, and 60C on load.
rampage 2 extreme
cooler master real power pro 750w
2xEVGA GTX285 vanila in sli.
4x Noctua NF-P12 fans. 1 rear, 2 top, 1 bottom.

I am think about upgrading these to liquid cooled. Will be using:
Pump: Swiftech MCP655
CPU block: Apogee GTZ i7
VGA block: koolance VID-NX285
Radiator: Swiftech MCR220 2x120mm

I am using a cooler master cosmos 1000. I want to mount the rad inside the case on the top, where the 2 stock 120mm fans are installed.
The fans will be Noctua NF-P12, about 54CFM (1300RPM)

So, the CPU and both vid cards will be on the loop. I am wondering if the radiator will be enough?

    you need AT LEAST a 120x3

    probably even separate loops.
  2. i7 needs a very substantial radiator. That little chip can dump a lot of heat.

    120x3 as overshocked suggested, make that your minimum size.
