I was almost on the verge of buying the 290 and the only reason I haven't so far is because of the high temperatures. AMD claims 95 degrees Celsius is not effecting the longevity of the card. I am the type of person who upgrades every 5 years so I really need this to last. Are these high temperatures safe and will they degrade fps over time or cause me any problems? I want to oc my gpu and I feel like the AMD would require some sort of water cooling system to do so, is this correct? Should I just stick with the safer EVGA GTX 780 superclocked w/ acx cooling? I feel like the AMD card is high risk high reward and the GTX 780 is just more expensive for the same speed.
