ANONYMOUS For those of you using PCI Cards with Panther, I tried this and discovered that it works great. I have AGP QE on my main video card, but run a number of additional monitors on 2 Radeon 7000 cards. Without PCI Extreme installed Expose was essentially useless for me; slow and clunky and ugly and horrid. With QE Enabled on the PCI cards, Expose works perfectly. This is really something Apple should have implemented. For me, QE has always worked well on PCI cards. Maybe they don't enable QE on PCI cards out of the box just because they want to sell newer systems.
