Hellpro

I used Throttlestop and MSI Afterburner for undervolting. The temps are OK (between 80-83°C for CPU and GPU under load). Maybe you can order it with an intel card if you ask them before buying it  
No i dont have any issues with the keyboard or trackpad. And the trackpad is really nice for windows device. I won't get the 4k Version, because you would sacrifice battery life and gain scaling problems. I saw them both and the 4k version is not worth it.

It depends on how well the skin for Android is made. My LG G3 was lagging HARD just pressing the home button with its snapdragon 801 (Known for overheating)

Since its a Octacore CPU it performes quiet well. But I wouldnt recomment it now that its released over a year ago. Im looking by myself into buying the Xiaomi Redmi note 3 because of a much better CPU, fullHD Display and 4000mAh battery Mabye consider that device.

Seems legit, I am skeptical of the battery IMO.  If it's everything it says it is, then it's pretty good.  Not high end (look at the camera & RAM), but it would probably do well.  Again, skeptical of the battery.  A Sony Xperia z3+ might do well, but it's a much higher price 

Yeah, I know, I just read the thread again and I missed this comment  I agree with you, not so sure about the cpu in the phone that the OP chose

I was talking about the other phone, I only talked about the Z3 in the last sentence lol.  The Z3 looks great - nice camera (OFC, it's Sony), and seems good.  I am skeptical of the phone the OP chose

Usually when I am trying to find out if a CPU/GPU in a phone is good, I google the name of the chipset and then wiki or something similar. I try to find in what devices this chip was used and read reviews. This time I looked for "MTK6592 device list". I don´t recognize anything this chip was in so further research is required. Here is the device list http://www.gizbeat.com/mtk6592-phone-list/
It contains mostly Chinese phones btw.

Don't think the CPU is anything special, sorry dude.

I honestly don´t know how good the MediaTek chhips are so I personally would stay away from them. They could be just fine but I don´t want to take the risk and have it come bite me in the arse later down the road like with the G3. I knew about the overheating issues that the Snapdragon 801 had but took the risk and now I have a pretty useless phone that lags very badly.

Ohh nice thanks for letting me know and thanks for all of your help
