Watercooling on HD4870x2

Hello, I am a happy with my processor the Radeon HD4870x2 Club 3D.
The problem is what is very hot, and it is very noisy.
So I thought a water cooler.
As I know nothing in water cooling I will seek advice.
My config:
-Q9650
HD4870x2 Club-3D
-2x2GB OCZ DDR3-1800
Realpower-Coolermaster M850
Antec Twelve-Hundred
Veloci-Raptor 300GB

My desires:
Water cooling a max. €200 to cool the graphics card only, a pump powerful enough to add a 4870x2 and a CPU waterblock and the latest entrant without any problems in my config.

THANK YOU!

I find it a little pointless water cooler just for the card but the 4870X2 but air cooling can be a better water cooling.

In it, you can easily save 240 rad at the back (or front), so you better part on a laying DDC, a Top EK, an integral Wb for 4870 X2 (cheapest of the moment that has not look suspicious) With a tubing 8/10 tip a cap 8/10 and 240 rad (genus magicool pro, if you're interested I'll put on sale a magicool Xtrem 240), not like any BIGT beginner always wants to do (this is a bad rad, dirt, narrow, needs high ventilation ...). When you want the proc to water cool better to add a 240.

And a 240 rad when he put his 2nd X2
Provided from a non-RAD 360? long-term, the spending seems less important.

At the same time I do a WC in a LianLi PC-75B 3-rad 160 (3 locations 2x80) and 1 RAD 360 (the "ceiling") at least the 3,160 on which I put.

Yeah but incorporate a 360 in a Twelve hundred ... to buy a 4870X2 then have to be crazy. For ventilators on the PA160 I doubt that this is a good idea.. low static pressure, large dead zone...
