Many Choices

Hi, I want to buy an inexpensive watercooling system for my pc. I found 6 different systems for $139.99 and under. The 6 watercooling systems are:

KINGWIN AWC-1 (http://www.newegg.com/Product/Product.asp?Item=N82E16835124005)
KINGWIN Aquastar AS-3000 (http://www.newegg.com/Product/Product.asp?Item=N82E16835124007)
Cooler Master Aquagate ALC-U01 (http://www.xoxide.com/aquagate.html)
Thermaltake Big Water SE (http://www.newegg.com/Product/Product.asp?Item=N82E16835106063)
GIGABYTE GH-WIU01 (http://www.newegg.com/Product/Product.asp?Item=N82E16835128011)
Titan NIKITA TWC-A04 (http://www.newegg.com/Product/Product.asp?Item=N82E16835192005)

Which one of these systems is the best performer? Is there any that I am missing? Noise is not an issue for me. Also some of these come with VGA Chipset Waterblocks, I am not really shure if I need it or not. Would a waterblock perform better than the fan I have on my Graphics card? My graphics card is a Radeon X800GTO Fireblade Edition (http://www.newegg.com/Product/Product.asp?Item=N82E16814102660) . It has a pretty good cooling system, but it does get very hot when I overclock it and run games that need alot of performance from the card, with a very heavy load it runs around 54c OC'ed, Wich isn't to bad for now but Im worried when summer comes it gets very hot in my house so I think it will run way to hot with the cooling it has now.

To me it seems like the best one is the GIGABYTE GH-WIU01 it is the only one of the 6 to have 1/2" tubing, but it only has a CPU waterblock. Followed by the KINGWIN AWC-1 which has 1/3" tubing which is the 3rd largest tubing of the 6, and it has a GPU and CPU waterblock. The pump on the Gigabyte pumps at 1.76 Gallons Per Minute, I cant find the gallons per minute for the Kingwin AWC-1 so I can't comapre that.
