Wondering if anyone can suggest any solutions to my awful frame rates I am experiencing at the moment...

System specs :

Athlon 64 Dual Core 3ghz
4Gb Ram
2 x GeForce GTX260's not running in SLi spanning 2 monitors, one monitor connected to each card
Vista Home 64

Running a single wow I have anywhere between 45 to 60 fps on max settings in game, however when I 5 box..1 main window on one screen and 4 on the other, my main screens FPS drops to 10 and lower. All 5 windows have graphics settings at the base minimum, and I have set maxfpsbk to 10 in keyclone for my slave windows. This however seems to make no difference at all, I am still experiencing the terribad framerates.

I am sure I should be getting higher rates with the rig I am running, and while I have a spare pc that I am eyeing up for a 2nd keyclone and just shoving the clones on that, I would like to work out why things run so badly
