Same here, I've been running CF setups since having 2x HD2900XT to 2x HD3870 X2 to 2x HD5870 to 3x HD7970, no real issue other than with the HD2900XT's. Sometimes, the driver refused to install, and I'd had to reinstall a few times for it to stick. But, the Cat driver has come a long way since, and I've had only minor issues every now and then, nothing game breaking, and nothing really worth mentioning. And before the nV boys jump on me, let's just say that I also have a pair of GTX670 in SLi in my 2nd rig, and other than minor issues every now and then as well, they're nothing to write home about. Also have a HD6990 in my 3rd rig, and dare I say it? It runs very nicely as well.....that's why, when I hear some peeps being quite vocal about ATi/AMD drivers, I go, "Huh? What driver issue?" And fanboys always going for, "But AMD driver sux the big one...." argument really have nothing else bad to say, so this is their mantra, their backup fallback line.
