Well depending on the graphics card you choose, your looking at either a triple 120 rad, or maybe could get by with a dual with high cfm fans. You could even do 2 small loops, but that's 2x the parts and 2x the cost/space/time to setup.
But that's up to you.
I myself would look into these though:

(if you get a 260/280)

or you can get the DDC pump with res top. That is the best performer according to martinsliquidlabs.com But that also gets pricey too.

Now depending on the rad you get, that really determines what fans you get. Some rads work just as well with med/low speed fans. Others need the high cfm fans. So that is kind of up to you.
Now more questions to answer while I sleep. lol
1. Do you only want one loop in your tower? Do you want one big loop, or 2 small loops?
2. IF you do one large loop, you'll need a large rad. Do you plan on mounting this internally or externally? If you do 2x smaller loops, same question.
3. A lot of this really depends on that hardware you picking out. Some of the GPU's/Cpu's run cooler then others. So if you get 2 cooler running parts, you may not need 2 loops, or large rads, so on..
So really think about the parts your gonna get first, and that will help make a lot of the decisions for you.
I'm signing off for the night, so I'll check back in the am.
