I am going to take the plunge and put together a WC rig. Going to go for some decent OCing of it as well or at least as much as the board/cooling/I can get out of it.

Mobo - Asus 650i
Ram - SuperTalen (6400) (4 1g sticks)
Chip - E6600
PSU - 850W
Graphics Card - 8800GTX
Case - U2-UFO Duality
DVD/Harddrive (not sure which yet of these but will probably just grab some at newegg that seem a good bang for the buck)

My first question is, since I am going to be stripping off the fan of the 8800 and putting most likely a MCW30 waterblock on it, would be better to just jump straight to the BFG Watercooled 8800? I am hesistant to do this since I have seen some feedback that the BFG version actually is a big restriction on the waterflow of your loop. Anyone had any experience with this?

The next few questions I have is I am going to be using a DDC-2 pump and running 7/16" tubing on my loop with a PA120.3 rad, YateLoon fans most likely and a reservior. Will one loop cool both the 8800, E6600 and NB well, keeping in mind I will like to be having plenty of cooling also to OC?
Another question, do I really need to cool the NB? There seem to be a lot of opinions stating yes and no.
If one loop is not sufficient to do this I assume adding a second PA120.3 rad will have little effect if its added to the same loop? Also keeping in mind that my case is basically an 18" cube, I have to believe that adding more rads to the loop, the loop will start to be fairly long... but I have no idea what length of loop will start to have an effect on the waterflow with the DDC-2.
If going with a second loop, I was thinking Res > Pump > CPU > NB > Rad, second loop would be pretty much Res > Pump > 8800 > Rad.
Is a MCW30 a good NB waterblock?

Lots of questions I know :) but I have been searching here and XtremeSystems forums for over a week, reading everything I can on WC and I am still unsure on my above questions. Thanks in advance for your suggestions and help.
