So what is the F@H client? An un-productive program? it drives my GPU's at 98-99% all day except when changing WU's. so that's what, a ten second (maybe) break every hour and a 1/2? (mileage varies by card) I'd say that qualifies as 98% 24/7. If you truly feel running Furmark is unrealistic then run F@H instead. it will utilize the cores quite efficiently and give the team some more points. Besides i'd like to see PPD added to the benchmarks anyway at least at stock clocks. give those of us for whom that is a consideration something to go on. and we don't even need the list of other cards and what they did. Just one line and/or screenshot showing the PPD.
We went with GPU-Z to record Temperatures and FurMark to heat the card up, we didn't use a preset time in FurMark instead ran it until the card maximum temperature and been reached and leveled off for a couple of minutes. Lets face it FurMark is unrealistic in and foreseen case because no game or productive program is gong to drive a GPU at 98% utilization all the time anyway
