Yeah, I have to admit I do have a bit more confidence from what I have read in the Mag3. The main goal was to try to keep a decent system at right about $100 give or take a little bit.
The benefit of the Via is that basically you can get two for the same price as the Mag3 with fairly close performance on a 1 to 1 comparision. For the few dollars difference if I was not going with the Via Aqua I would probably jump to the Mag5 which should be able to achieve decent flow through most high flow required waterblocks.
I am currently using a Hydor L35 which would most probably also make the grade for right at the same price. It also only puts out 23watts which would be pretty nice considering it would add a wee bit less heat to the loop.
If you can think of any other ways of saving to break that $100 mark and wouldnt hurt the system too much please kick in
