need help choosing cpu/gpu blocks

iv decided to get watercooling and i need some help, for now im wondering which cpu and gpu blocks to go with

for the cpu block which would perform the best out of the maze4, swifttech apogee, swiftech storm

and for the gpu, maze4 or swiftech mcw55

or are there better? my budget is $150-200 for everything so silver blocks like the storm g5 are a bit too much

thanks in advance

hm would the storm have any trouble with flow or could the holes get blocked from any impurities in the water such as dust?

i also need some help choosing a radiator and pump, im thinking of using 2 single fan radiators so they can fit inside my case between the black ice x flow and the black ice 2 pass standard verisions which would perform better, and is there a difference between the pro and xtreme versions

thanks

ah ic hm for the additives would prestone anti freeze be enough or do i need some kind of algaecide with it?

thanks

A common misconception about anti-freeze is that it keeps cools water cooler at high temperatures. Antifreeze does not cool water at high temperatures, it simply increases the boiling point. The only advantage to using antifreeze is it's anti corrosive properties.

Don't use it.
