For a while I've had dual-GPUs in my system, Ti4800SE Primary, and 4-MX440 secondary

But I noticed something

On my Dell 8200 system, I used to have those two cards in that box, I ran Quake 3 at around 150fps (on the 4800SE of course)

Then I remembered about what it was like when I was using a GeForce 2 MX 440 as a primary (don't laugh) and a Voodoo 3300 as a secondary, how I only got around 70fps

But now, only the GeForce2 MX card is in there, without any secondary GPU, and I get around 100fps

So basically, does having a secondary GPU installed and running (And connected to a monitor) affect the performance of the first card?

Well perhaps not as directly as that...but at some level the cpu has to have the drivers loaded for the gpu, and the drivers (or parts of them) tend to live in l2 cache as they are used quite often for even 2d stuff. That might indirectly affect performance in a fairly important way...

I don,t think so they 2 cards well not render the same at all.
