Radiator comparison question

[Dice]

I am looking to water cool a PC I am building. The goal is to OC to the limits of the mobo and GPU. This will be a mid-range gaming machine. I have an older rig which has been underwater for a couple years now, and am comfortable with WC. Also, low fan noise is preferable as the case will be living on my desk, not on the floor.

The PC:
e6420 (OC goal = 3.2Ghz@ 400Mhz FSB)
1 8600GT (OC goal = whatever the card will do till I can afford a replacement)
I plan to replace the GPU with an 8800 series card, and include it in the loop

The loop parts:
TDX for 775
Maze5 for GPU
DDC with small res top & 1/2" barbs
NZXT Rogue case

My question is:
Will a Thermochill 120.1/BIGTX-120 be adequate for this application, or will it need a larger radiator?

I only ask because when I stopped spending money on WC parts a couple years ago, 240mm+ rads were required for a good CPU/GPU loop. The modern rads seem like they are more able then their older counterparts. That and with the Rogue, space is at a premium. I do know that with modification the Rogue can accept a 240mm radiator, but I will only do that if needs be. (It takes considerable modification to do so.) So, thanks for reading and what say you?

You need to go with a dual rad to handle both a CPU and GPU, especially since you want lower speed fans. You would have to crank up the fans on a single rad, unless you used a PA160.

Ok, so the same is true now that it was then. Not the answer I wanted to hear, but I'm glad I know how it is before dropping cash on a radiator which cannot effectively cool what I need it to.

billb- Thanks for the links. From the info in those resources, I was able to figure out exactly which components I need to cool the system I am building, and get a realistic idea of how much heat the parts I am using will actually generate.
