Nowhere was it stated that the system info displayed in GUI is to replace CPUZ/GPUZ, everyone uploading without them will eventually get the scores reported/removed. I have (temporarly at least) removed the Start CPUZ/GPUZ buttons as it was buggy sometimes, and looking for a cleaner method.
For your 7970/7990 problem, can you go to Device Manager and tell me the PNPID of your graphics card? Looking over the code, that happened because your 7970 does not use SubsysID 3000 so it was defaulted to 7990.
