Should I start with CPU water cooling?

In the process of building a new PC based on a i7 920 and dual GTX285's

I'm looking at doing a water cooling setup with the following:

(Don't have all the part numbers on hand )

Triple Rad (Looking at the Feser at the moment)
3x Noctua Fans
CPU block (Swiftech GTZ)
1/2 inch ID tubing (Feser as well, maybe a smaller ID?)
Pump (Looking at suggestions)
Reservoir

That should be sufficient to keep my CPU cool, obviously I'm looking for a maximum OC so I'd keep the triple rad designated to the CPU.

Question, should I add a second loop to cool the 285's? I'm a relative noob to watercooling, so I'm thinking I should start with the CPU and possibly add the GPU loop down the road.

If I do go with a GPU loop what are the benefits to a full cover waterblock vs a waterblock + ramsinks? Any suggestions?

CokenBeer, your on track, perfect. That rad will give you great CPU temps.

And yea, you'll need a seperate loop for the two GPU's, they generate a lot of heat. Enough they would effect the CPU loop if you added them. You'll need a 120x3 rad.

Any stay away from the Coolit stuff.

Your very close to my setup I'm building. Linky.

One more question for people! I know certain Radiators work better with a high CFM fan and others work well with lower CFM (like the Noctuas).

What's suggested for low CFM?

Probably gonna go with the Feser X-Changer rads, they're expensive but seem to offer the best performance.

Also seems that they work well with a lower RPM fan Noctua P12 is what I plan on using.

Any cases which will allow me to put both loops internally ? If not I'll get a radbox and mount one in the back!
