Hmm, what the hell are you guys talking about? I get my choice of refresh rates of my Samsung 900NF and my Sony G520 using a PCI ATI Rage128 card and an nVidia GeForce3 (both refresh at 85Hz). Moreover, my girlfriend is running 85Hz refresh rate on her PCI ATI Rage128 Pro ALL-IN-WONDER on her Sony monitor.
You talking about under games? Why not download the nVidia refresh rate fix for WinXP ???
EDIT: You guys download any "driver" files for your monitor? I don't see why you can't get a decent refresh rate...also, NEVER use the "optimal" setting if that's available--I always set it to whatever I want my refresh rate to be.
