3 wows, 2 screens. How?

Hi to everyone =) A litle over a month ago I started dualboxing, true raf got a secound account and transffered my late 40ish shaman to it. Together with my early 40ish mage I've now got to 60 :D ye, not fast I know, but it's been veary litle gaming latly, work, gf, drivers license, the days are too short :(
Anywho, I also got a 60 paladin on acc 1, now I'm thinking about moving this char over to a third yet to be created account. My only problem is, where should the screen come?:s I got two screens on my one "not-great-but-yet-awasome" dell computer, which I know can handle it (tested 5, nps), currently running 2048 x 768 could go higher, but first; less gpu stress on lower res, it seems. Secoundly,dunno how to run wow at higher res in windowed :s anyways it's working fine now, with acc1 on screen1, and acc2 on screen2, obviously. But where should I put my third?
I'm going to have shaman-paladin-mage, shaman heal, paladin tank and mage spank. I'm was thinking I should put the mage in a relativly small screen above the shaman, kinda PiP, but one thing is exactly where and how big. Secoundly, sometimes I could have good use of controlling the mage directly for a few sec for some aoe. Not realy a big issue as I will try avoid suck things, but stil with this setup I think it can be veary usefull. But most importantly, specially right now, where to put that screen.

Ok, this seems to be a rather not-thought-true post, and it kinda is. Havn't spent time on how to type it etc, just got my issue hoping to get some help =)

So to sum up, how should I put 3 wows on 2 screen? tank-healer-dps. Res 2048x768 (each screen 1024x768 ) in case someone got a setup and can provide exact numbers on how far down and to the right =) or kinda.

Enjoying Multoboxing so much, now aiming for more <3 5 to come =)

Edit: also, if anyone want to trow in, it would be great with some cast sequence macro for the pala and mage for 1 button smashing true everything. And spec for the mage =) currently fire. No, havn't looked at the wiki about that yet, but that's to come secoundly =)

I played three chars at first aswell. Then I used one screen for my main, and started of with using 1/4 of the other screen per instance of wow. But I had such small screen with low res back then so I feelt the windows were getting so ridiculously small making it hard to just read text from them.
Stretching them horizontally just fattened everything out and looked stupid, but when I tryed stretching them vertically the font was treated like it should be, but ofc they looked a little skinnier and so. ;D

Short, if you're not happy with just having two wows covering 1/4 each of your second screen, you could acctually try and stretch them to 1/2 each (vertically).
