Refresh rate problem with HD5850

I just installed my brand new XFX HD5850 and I can not for the life of me get it to go above 60hz refresh @ 1280x1024 (or any other resolution). I did not have this problem with the old 7900GT.
Any suggestions? The screen flicker is already killing my eyes.

In Catalyst Control Center, go to Desktops & Displays, find your way to the resolution changing page for the screen, and see if you can set it to 85hz (use the Force button if you need to, it won't hurt the monitor).
Edit - also, make sure you find and check off the box that says something like "Use EDID for display capabilities".
Also, in my ATI control panel, there is no way to force it. Only have that option open to me through the Windows display panel.
Just found that box, turned it off, still nothing.
Here's hoping it's still just some stupid tweak that has to be made somewhere. I feel your pain with CRT 60hz - I find it uncomfortable too.
Unfortunately, my gaming rig is still (temporarily) out of commission due to my accidentally making its RAID5 array unbootable. I should have it solved by sometime tonight though.
Right click Catalyst control center > Select 1. ATI Radeon HD 5850 > hover over it and the next menu appears, select 3D Settings > then on the next menu "Wait for Vertical Refresh" is it set to "Always On"?
Default is set to "application decides" forced it to off at all times.
Right now I am ghetto rigged hot swapping monitors so that I can get 75Hz on this monitor. Wish I could get it up to 85Hz, mainly because thats where it is designed to run and the picture fits better.
Be back in a bit with a fresh install.
Also, after getting back in touch with AMD over this issue, they say it now may just be this monitor, since the A90 is correctly identified and it is almost 4 years older than this G90f and a fresh install with minimal components still renders essentially the same result. At least next month I get to use a 24" HDLCD while house sitting; should look fantastic with this HD5850.
