I'm another voice in the lower scores department. I added another gig of RAM (3 total) and ran NovaBench. Scored 189, couldn't upload error: Results rejected as invalid. Went back to original config, score increased to 202 (significantly increased memory access speed but far from the 258 I got before. PC seems to be working fine. Since the original tests I ran back at the beginning of the year I have installed iRacing (now uninstalled) and rFactor. I uninstalled NovaBench , downloaded another copy and reinstalled; same result. Suggestions to reformat and reinstall the PC are ridiculous. The PC runs fine, the results are off. Maybe a MS update or a virus is to blame?
