The fonts are beautiful for me (1680x1050, nvidia 250GTS), thick and smooth. I did hear alot of complaints in the chatroom though, must be some wierd specific resolution-to-monitor-drivers bug?
Same setup (260 Core 216, but close enough) and I've got no problems with the fonts, which is unusual: I almost always find fonts in everything too small to read comfortably. But no, haven't noticed any problems.
