I am running an AMD dual core as well. I have had nothing but good experiences with AMD in the past but they are just not as powerful as Intel now. As far as the spinning clipboard, install the AMD dual core optimizer patch and it should clear that up. It did for me at least. I ran AH on vista for about 3 month with no problem then everything went T.U. with the new patch. I had warping, freezes, etc. I tried everything and eventually had to set up dual boot with XP pro x64. Now it runs beautifully. Try some websites like newegg or tigerdirect, XP is REALLY cheap now, especially the OEM versions.
