I want to have 3 monitors setup but the third doesn't need to be hi performance. It's mostly for older video games (that don't display well on a hi res LCD, like Start Craft).

If I mix a newer Video Card, like a:
256MB NVIDIA® Quadro® NVS 295, 2MON


an older PCI-slot video card video card

Is that going to degrade the performance of the newer card?

It could affect the performance of the newer card because they all share the same bus to the processor (on a 1P system). I wouldn't expect it to be noticeable, though. The processor bus bandwidth is much much higher than the PCI card bandwidth

What is a 1 P system? (1 CPU ?) – Clay Nichols Sep 30 '09 at 5:35
Yes. 1P = 1 processor socket -- a typical desktop/mobile motherboard. On a 2P or higher system, the PCIe video card could be off a different processor than the PCI card (at least with AMD architecture -- I'm not sure about Intel Quickpath) and then there wouldn't be using the same processor bus. – hanleyp Sep 30 '09 at 12:16
