The guys at Hexus take an X1650Pro, a 7600GT, & an X1650XT that are all passively-cooled, & see which one deserves a spot in your next silent rig. The "stock" passive coolers on cards these days have come a looooooooong way since companies first started using them, that's for sure.

"DX10 gaming is still a little way's off so partners still rely on DX9 parts to make up the bulk of their sales. In the name of differentiation, larger AICs have taken it upon themselves to design and market passively-cooled cards based on popular GPUs."
