Forums -> Multiple monitors -> Radeon 9800 Pro AGP + Radeon 9100 PCI

Strange problem running both a 9800 Pro AGP and a Radeon 9100 PCI in the same system. The PC works fine for everything but intense 3D graphic games. I have 3 monitors hooked up (2 on the Radeon 9800 and 1 x Radeon 9100). When I play a 3D graphics game (on the 9800 primary display) I eventually end up with strange artifacts flickering on the screen and then all hell breaks loose and the PC usually locks up. I thought it was a heat related problem because it only occured when the game was running for 5min or so. I replaced the 9800 card and the new one is doing the same thing. I then pulled the 9100 out of the system and everything is now working. I can't see how the 9100 could affect the 9800 3D graphics but it appears to. Only other thing I can investigate is if my power supply (300watts) is just not enough.
Thoughts?

Yes, the heavy 3D usage could overtax the power supply, especially with the extra card in there, but also make sure your BIOS and drivers are up to date, and you might also want to try using a different PCI slot for the one card.
