I had been looking around for a mechanical keyboard with no numpad and then I see this. The "Quick Fire" label is a bit strange, but I can overlook that since this keyboard meets my usability requirements.
You can't crossfire a HD 4770 with a 4730. In order to crossfire different cards, they have to be based on the same GPU. The 4730 is based on a cut-down 55nm RV770 whereas the 4770 is based on the 40nm RV740.
Updating to these drivers gave me the infamous "Zero Display Service Error." while installing the drivers. It then continued with the rest of the Catalyst installation and everything seems to be running fine. Any ideas on what causes the error?
