So I've decided to return as a 3 man for scenarios and Mammoth passenger BGs.

My goal at this point is to get 3 monitors running a wow instance each on ultra settings.

Each monitor will be powered by a video card.

The current system has:

CPU - I7 2600K
RAM - 16 GB DDR3
Hard drive - WD SSD 125 GB
2 * GTX 460s

Windows 7 64 bit OS

Nothing overclocked, air-cooled 900 case.


I noticed that the current system cannot do 2 instances at ultra settings without dipping to single digit FPS in capital cities. So I already figure my video cards need replacing. Is this normal? I know that window mode has something to do with that.

What kind of performance should I be expecting out of a video card update for this current system? To my knowledge neither CPU nor RAM are challenged by the three instances running. Is it better to do this off a single card or should I get 3 cheaper cards?
