I'm currently overclocking my GeForce GTX 560 TI (the version that came pre-overclocked to 900 - engine, and 4200/2100 memory) a little bit, and I was just wondering whether I should Use OCCT or Furmark regarding temperatur-readings. Somebody says Furmark is insanely high on temps, and that there's no point using that as a reference when gaming or using the GPU otherwise. I don't know about OCCT, but I'm guessing the max gpu temp in OCCT is a bit higher than max temp in actual use. How far would you've gone with the temp (as long as the testing is fine and stabil otherwise of course) in OCCT? I'm currently at 82 degrees in a default 1hour test with error checking. And I'm at 930 engine and 4226 memory. I was thinking about investing in a GPU-cooler, but I'm wondering if I really need to...
