Testing of the ENGTX570 DirectCU II will mean running the card through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors in order to gauge its performance. The games used are some of today's newest and most popular titles to give you an idea on how the cards perform relative to each other. The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing with the exception of the 3DMark Vantage testing where PhysX is disabled in the NVIDIA Control Panel when applicable. I will test the card at stock speeds and then overclocked to see how much additional performance is available and to determine if it can run with or faster than the current fastest single GPU cards on the market. Of course, all settings are left at defaults in the control panels of each respective manufacturer except where noted. I really want to see just how fast this card can fly!

Well needless to say, I want to improve on the 10MHz overclock that ASUS ships stock. With such a massive cooling system and the voltage tweaking capability baked in, I have high hopes of success with this card. I began in earnest trying to find the upper limits of this chip. Opening up ASUS' bundled Smart Doctor utility with GPU-Z to verify settings, I set the fans to 100% and ran MSI's Kombustor utility to warm up the card and provide background stress as I push the card. I began moving up 10 MHz at a time, leaving the voltage at stock for now, allowing five minutes in between bumps to verify moderate stability. I continued doing this up to 865 MHz, where I finally crashed. I went back down to 860 MHz and let it burn in for 15 minutes with no errors and the GPU core sitting at a mere 62 degrees Celcius, I knew this was going to be fun. I nudged up the voltage and continued, swapping between voltage and clock speed as I went. I maxed out at a mind-numbing 925 MHz on the core at 1.1v and 988 on the DDR5 running at 80 degrees Celcius. This card's a spunky one, boys - that's nearly 200 MHz over reference speeds. Time to bench it.
