I have recently upgraded my computer and am finding that my2001 version of Caddie 8.0 CAD program causes the screen to flicker in a way that it did not on the old computer. My new computer (4 gigs ram and XP) has integrated graphics so I am thinking of getting a new PCIe graphics card - anyone have any recommendations. I don't use computer games, which is what cards are optimized for it seems. Any sugestions welcomed.
