Upgrade to Release Preview - CPU incompatibility?

Q

I tried upgrading from 8 Consumer Preview to 8 Release Preview and it now tells me my CPU is not compatible. Anyone else seeing this? My understanding is that 8 is compatible with anything 7 was compatible with.

Dell OptiPlex GX280, I installed the CP from a disk, but was attempting to upgrade to the RP via the web installer.
