Single MCP655 and PA120.3 enough for this?

[003]

Right now my loop is cooled with a single PA120.3, and I use a single MCP655 pump on the highest setting. The loop cools my chipset, CPU and video card.

When the 4870X2 is released, I am going to buy two of them for quad CFX, and they will be included in my loop as well (replacing the old single video card). I know there are no hard numbers here for a definitive yes or no, but will I most likely be able to cool everything using the single PA120.3 and MCP655, or would I need a second pump and/or a bigger/another radiator? Everything will be overclocked as far as I can go.

4gpu cores and a quad cpu, all overclocked should be putting out a lot of heat..if i were you i would just add a 2nd PA120.3 in the loop. pressure drop is very low so it shouldnt affect it much...Your best choice, although more expensive, would be to run a dual loop to cope better with all the blocks in the system

I second this, you may not notice a huge difference from your temps now but without the second rad you will definately notice a difference, and really no one knows what type of heatload the new 4XXX series will put out, so it's still hard to judge just how much more cooling will be needed.
