You may find information on the rumored ATI graphics card problem.

My board is $96, so it is somewhat more expensive. I also don't overclock. People have reported problems with using certain kinds of system memory with integrated graphics. I use Crucial and haven't had any issues, but if you have your own card it wouldn't be an issue.
