I am getting ready to rebuild my system, I have been running 3 25" monitors on an HD 5770, works great. But I dual boot Win XP/32 and W7/64. I boot to XP to do e-mail, browse ect... and I boot to W7 to use the 3 eyefinity setup. I only do a flight sim or other games maybe 10% of the time, and would like to install W7 only, but would like to change the display from 3 to 1 on the fly. Anyone done this yet?
