It seems the CPU-Z team is hard at work and planning on bringing some big updates with the 1.52 update that the plan to release sometime in the next month.
First on the list of new features is the new Graphics tab. This will provide basic GPU information within CPU-Z, although it is already reported on the validation page.
Second is that there will now be a native 64-bit version of the application, which many have been asking the team to release for quite some time now. Third, the CPU-Z window has been widened a little bit to accomodate Intel's new, slightly wider, logos.
Finally, CPU-Z will have a new Validate button at the bottom of the window. This should make it a little easier to submit validation information.
