Screen Refresh Rate too low

I installed Ubuntu recently on my AMD 64 3000+ computer. I have a Radeon X600 series graphics card. When I go into the monitor settings on gnome or KDE it will only let me go up to 60 Hz, whereas on WindowsXP it will go up to 200. I changed the xorg.conf file and changed the monitor settings so the refresh rate goes up to 150. After I did that I went into gnome to see if it changed anything. There was an option for 86Hz, and when I did that the quality of the picture was degraded, and it was smaller.
There is a possibility that it is related to another line I changed in the xorg.conf.
I had to change one of the graphics cards settings, otherwise Ubuntu wouldn't start at all.

Option "NoAccel" "true"
So I don't have hardware acceleration on my card. (by the way, if anyone knows a way I could fix that it would be great)

So if anyone can figure out how to get a higher refresh rate, or get my graphics card working with hardware acceleration, it would be great.
