I can offer stabs in the dark.
If we can get LHG in here he might be able to give you an APPROXIMATION. I have long since given up(long, LONG, ago) trying to guess performance in a specific fashion. So I do a lot of guessing.


I am unsure how much power the X1800XT sheds(assuming you are using your sig video cards), I would guess about 70 watts + or -. Saw someone swearing that it draws 100 watts of power, seemed a little high to me. But, then again, I am not familiar with it, and besides I am guessing.

So between the two of them they would produce about as much as a maxed out CPU.
From what I have heard the PA160 is plenty for a single hot CPU.(assuming you have a relatively ok fan on it)

Your choice of water block, the Maze4, is interesting. Especially with the 50z. If all you are going to cool is the GPUs then you probably don't need to worry about flow too much. Since that is the primary reason I have heard for getting the Maze4s. (low flow resitance and not much else)

So I would say your loop would work.
