Dual 2D/3D video cards, one monitor

[WhoKnowsWho]

Okay, say you have a AGP ATI Rage 128, and get a Voodoo3 2000 PCI... Can you use a y-cable to connect a single monitor to both outputs of the video cards and not cause things to go nuts? I am guessing you would have to disable one or the other in the windows device manager to make sure which one you are using and to make sure they don't conflict. Anyone done this or know if only bad things could come out of a combination like this? Thanks.

DONT use the 'Y-CABLE' idea...it might blow ur cards away...
try to look for monitor data switch...i m using 1 here....4 ports....
or if ur monitor supports BNC/D-SUB, this is better...
