FWIW, these cards do not all apparently make this squeal. Mine is very quiet, almost as quiet as my old x1950xt with a Zalman vf900. In fact, it's so quiet and cool enough that I may not install the vf900 on the 8800gt. So far, so good. :D
OK, noob question here. I got in on the 2x1GB ddr2 1000 deal about a month ago. I'd like to move up to 4GB total. Would mixing and matching with this kit work OK?
