Dual Monitor Performance

[lyster]

How should two dissimilar monitors be hooked up to two dissimilar video cards from an overall performance point of view?

Here's my specific setup (but a referral to a general article on the subject would be fine too):

Monitor 1: 15" LCD Flat Panel

Monitor 2: 19" CRT

Video Card 1: GeForce 3 AGP with 64 MB DDR

Video Card 2: ATI Radeon PCI with 32 MB SDR

Motherboard supports designating which monitor is primary.

Currently I'm running the lesser performance video card 2 as "primary" both for boot purposes and for Windows XP (yes, that's my OS) purposes. That card 2 is presently hooked up to the 15" LCD flat panel display.

I've set it up in several different ways, and it doesn't seem to make much difference. It works any way it's set up (thank God). Just curious if there is a preferred way to do this and why.

My opinion, unless the lcd panel is a very fast one that can keep up with the card I would connect it to the ati card. If I am not mistaken the response time on lcd monitors isn't fast enough to keep up with the gforce 3 and would actually force it to slow down waiting for vsync.

The Gforce3 I would hook up to the crt for overall performance.

I guessed right on that one! Does it matter which card is "primary" or "secondary" (either in the BIOS or in Windows XP)?
