Video stutters with multiple wows open in windowed mode.

here's my problem. I'm running a 3 monitor set-up with 3 wows, 1 on the main monitor 2 on the right side monitor. the main monitor is powered by a gtx280, and the secondary monitors are run by a 8800GT. when i have a single wow open in windowed mode the video is flawless, the instant i open another wow on the secondary monitor the video stutters on the main, its very noticeable and quite annoying. these are 2 work arounds that i have discovered to work, the first is running my main monitor in fullscreen mode which is no good for multi-boxing because of the alt-tabing that needs to be done, the second is running all 3 wows on the main monitor which is no fun when you can take full advantage of a 24inch dell ultrasharp, +i can't find a good way to make it work on a widescreen monitor. originally i was running nvidia driver 177.41 which supports only the gtx280, i have updated to the new beta driver 177.92 which was released on 8/26/08 and supports every card from the 6series forward, this didn't fix the problem. tried vsync, moving the wows to the other secondary monitor, resetting all maximizer and wow start-up settings, and nothing seems to work to where i can have the 2 wows running on a secondary monitor while using windowed mode. so i came here looking for help or suggestions. any help is appreciated. here's my full specs.

Windows Vista Ultimate x64
intel core 2 extreme qx9770 OC'd to 3.8ghz
8gb DDR2 800 OCZ RAM
EVGA GTX280 1GB
EVGA 8800GT 512MB

I'm getting the same issues with 2 wows, the seccond another one is opened they both start glitching and produce "artifacts" in game.

I havn't found a work around on my machine. i'm working with 2 monitors powered by 1 x 9800gtx(3.0ghz core 2 duo proc, 4 gigs of ram) by all means this rig should handle 2 wows. It only goes up to 54Cish on load with both wows.

if you haven't done it already, you should create keyclone commands ... not only does it help with start up and layout, but it also allows you to easily set the maxfpsbk and maxfps. if you don't, then all wows will attempt to get 999 fps... killing your fps.

while you are at it, you should also reduce your details (search the wiki for a few macros)

i'm running 5 wows on a single monitor getting 50fps each. i have 2x 260s in the box... each driving a different monitor... but if i put 4 on one and 1 on the other @ 1280x1024... i'm lucky to get 10/30 fps. i have been told it's the 750i mainboard which is having the problems (by design actually).
