Our review of the NVIDIA GeForce GTX 295 showed that it was far superior to the the standard GeForce GTX 280 while consuming only 23% more power (289W vs. 236W). On average, it was about 50% faster than the GeForce GTX 280 and 80% faster than the GeForce GTX 260. That's a significant boost in performance, something NVIDIA really needs to spoil ATI's winning streak. Of course, the GeForce GTX 295 has a really hefty price tag, which makes everyone wonder if it's worth buying when there's a virtual fire sale of GeForce GTX 280 and GTX 260 cards. If the GeForce GTX 295 is really overclockable, then it might be even more worth buying than the GeForce GTX 280 and GTX 260 cards which are still using the older 65nm GT200 GPUs. Let’s find out!

Did you guys take any temp readings during the overclock? I'm curious whether these overclocks will be sustainable over long periods of time while gaming. I've read a lot about how hot the 295 runs even at stock clocks.
For some reason, the card did not give us any temperature readings. However, the overclocked frequencies we quoted are the highest, STABLE clock speeds. As long as it shows some signs of failure (e.g. graphics artifacts), we would reduce the clock speed, even if it didn't actually crash. We also reduced the clock speed by a small margin to account for any changes in temperature and voltages (as recommended in the guide. So, our clock speeds are rock solid, for our card at least.
