Closed GPU loop advice needed
 

I'm not sure if this is a regular thing, or not, but I want to set up a dedicated GPU loop to cool my smokin' x1900xt. I have two major objectives for this:

1. maximum cooling/price
2. extremely low noise operation

My system is housed in an Antec P180, so a PA160 will not fit where I'm placing the rad (up front). Current component considerations:

Radiator:
Swiftech MCR120 Quiet Power $30
Thermochill PA120.1 $85
edit: also considering:
DTek Pro-120 combo $40

-is the price difference worth it?

GPU Block:
Swiftech MCW60 $60 (w/ ramsinks)
DD Maze4 GPU $45
Dtek AquaXtreme MP-1 $45

-which is the best 3/8" ID block? Why? Evidence?

Pump/Resivoir:
Swiftech MCRES-1000P $95

Fan:
Scythe S-Flex 1200RPM temp controlled w/ ABit uGuru $14

4ft. Tygon 3/8" ID

Input, suggestions welcome.

Rads will perform 1-2 degree C within each other. Check out BillA's test on rads on swiftech website.

Swiftech is best bang for the buck. Heatercores are PITA and requires shrouds and modsto the case. I wouldn't get pa120.1 as it doesn't seem worth it when you can get pa120.2 or 120.3 for not much more.

Get more tubing. Its only $2 a foot so get more just incase you decided to add more parts.

GPU blocks should perform pretty much the same. Swiftech seems to get the best flow rate and has sweet ramsink package but I personally won't buy their products.

No one has done a reputable side-by-side GPU test.
Robotech still not interested. Sigh.
