Hey, I have the a GTX 860m 4GB Maxwell. Now I have Overclocked mine to +135 Core and +500 Memory and my max temps after 5 hours of gaming is 72 Degrees. I've never gone past that since I got my Lenovo Ideapad y50 last year and it's been Overclocked nearly all the time since. I used to be able to get +1000 memory at one point but nvidia has prevented me going that high with one of their driver updates. Anyway I live in Dubai and my desk is extremely dusty, along with the AC being broken and my room being 37 degrees, so I'd expect my temps to be the highest.... Didn't expect this at all. I have a YouTube channel, NemesisTechBoy. Check there for videos, I'm gonna start pushing some in the next few days for people to compare their own benchmarks and temps to mine
